...if only more people understand how SPAMmers gain access to your address, it may eventually help to greatly reduce, if not put an end to the problem of SPAM.

All of us have wondered how on earth we end up getting onto so many SPAM lists. Would you believe that gentle, loving, very well-meaning friends and family are responsible for a large part of it? There are two very simple, but poorly understood problems that invariably result in SPAM. More often than not, these two mistakes are made in a single e-mail, which greatly increases the likelihood of SPAM.

1. Sending e-mail with addresses "In the Open" rather than "Blind". When you go to address a e-mail, by clicking on "To", your Address Book appears. All of your contacts appear in the left hand column. On the right are three boxes labeled, "To", "Cc" & "Bcc".

If you are sending a e-mail to multiple recipients and put all of the addresses in either the "To" or "Cc" boxes, every recipient will be able to read, (and use), the address of every other person to whom the e-mail is sent. This is referred to as sending the addresses "In the Open." If you are sending a e-mail to multiple recipients and put all of the addresses in the "Bcc" (Blind Carbon Copy) box, each person will receive it -- but none of them will be able to see the address of anyone else to whom it is sent.

Many servers will automatically reject any e-mail that lacks an entry in the "To" box. For this reason, if you use "Bcc" for the addresses of those to whom you are sending the e-mail, you will need to place your own address in the "To" box. This will ensure that everyone receives it -- but yours is the only address that appears "In the Open."

2. Using the "Forward" button, without first deleting any and all previous addresses that appear "In the Open," All of us receive items that we want to share with friends and family. All too often however, people find it just too easy to hit the "Forward" button and then add the "In the Open" addresses of their own friends and family.

Just recently, I received a single e-mail that contained almost two hundred "In the Open," readable, SELLable, e-mail addresses. It had been forwarded five times and not once had anyone bothered to remove any of the previous addresses or use the "Bcc" line! To a SPAMmer, this is pure gold. He can sell every address on the SPAM market. And the SPAMmers not only use them -- they then reduce their overhead costs by selling them again to others. And suddenly, everyone is wondering just how on earth they are getting so much SPAM from around the world -- and much of it would make a sailor blush. The original sender of this e-mail knew only two of the people on the first "Forward," and not a soul on those that followed.

The e-mail you are now reading has been received by over two thousand other people on my mailing list, but it is totally worthless to a SPAMmer, because all of the addresses were entered in the "Bcc" line and the only address anyone can read is my own. Now! As to "Other E-mail Courtesy."

If you feel that the information I have provided is worth sharing with friends and family then, for goodness sake, care enough about them not to impose a constantly growing number of >>>>>>>'s on every line, every time it is forwarded! "Click," "Drag" to highlight and "Copy" onto a new e-mail. The only thing on the Internet that is as nearly frustrating as SPAM, is trying to read what would otherwise be a beautiful piece, while trying to ignore the >>>>>>>'s on every line

I'm not going to bother reading all that up there, but here is how some of the spammers operate:

1) they extract emails from websites/forums using email extraction programs.
2) after extraction, they run these email lists (usually text files) through "cleaners," which remove duplicates
3) load the email lists into mass-emailers, which can send thousands of mails per min.

You having your email address in your profile on a public forum are also a very easy target for spammers.
Posting on newsgroups or having a Hotmail account are other good ways.

I once got a brand new hotmail account. I never gave out the address. I didn't even use it for a few days. When I finally went to use the account, there were hundreds of spam messages. I will not use hotmail again.

Hotmail is utter junk. I hate my hotmail address but everyone has it.

I see some emails that are just sent to me by people's spam programs that randomly guess on emails. If your email is bob@hotmail.com you may see it go to bob@hotmail.com and also in the CC you'll see bob1, bob01, bob02, etc. etc. they just pummel all the possible different versions of it so there is no way around it.

Yep, that's how a new Hotmail account collects spam. Spammers can send emails by the thousands so easily, they can afford to guess at addresses (especially on places like Hotmail, Yahoo, etc.) They don't care how many bounce because they spoof the return addy so they'll never see them.

Another major contributor to spam is when people go to some "fun" website, and fall for the "Tell a friend!" crap. Isn't it bad enough that people forward stupid emails? (Yesterday I got one of those "forward this 20 times and Target will send you a gift certificate!" ones). Do they have to willingly supply my email address to crap websites just because the site asked them to?

I KNEW someone was going to say this. I did the same... not a single SPAM message. Not one.

Actually spam is the reason I have a Hotmail account. Any website that wants an address, in fact almost any company that wants my email gets the Hotmail address.

I guess I'm lucky - I've been using the same hotmail address for a couple years now and I may have gotten a total of 10 spams through that time.

Hmm... Ive had a non-free email account for 2 years now and until a month ago, I could count the number of spams on 1 hand. Suddenly, Im getting lots of dodgy porn and pyramid scheme mails. The only difference: I registered for CeBit Australia with my proper email. When I got there, I got given this scannable ID card and entered several competitions using it. Now, i get spam. Its a bit disturbing that the companies that I let see my email (Intel, Siemens, Samsung, PC Magazing etc) would be selling my email addy.

SPAM will be hard to stop until harvesting emai addresses is put to an end.

Its rather simple to get a HUGE mailing list by sending mail to a massive amount of possible email addresses at any given ISP...The mail servers will then return "unknown address" responses to addresses that do not exist...These addresses are struck from the list. This method is typically a VERY efficient way at gathering a huge list of email addresses for SPAM lists.

I liked the Bcc comment, i had no idea what that stood for until now, and will use it regularly. This quote reminds me of something a friend of mine said to me last week "what ever happened to all the straight heterosexual pr0n spam?, why the Heck has it turned into nasty junk like beastiality?"

I use yahoo and have to migrate accounts occasionaly, i had a spam addy and a regular addy, then the regular addy was taken over by spam (300 a day) so i got another one, now what used to be my regular addy is now my spam addy. Its sad.

There was an article in the USA Today newspaper about someone who spams as a job. Heard he was making about $30K/month. Any links to it?

Meh, this isn't rocket science, nor any sort of a revelation. I've given-up trying to educate people on this, though I dutifully remove lines of >>>>>>>>>>>>>>. and addresses every time. I tend to forward things only to a small group of friends/family, too, so I deliberately don't use Bcc, because they often like to reply to all who are in on the forward.

I realize this doesn't stop spam, but I have a filter set that automatically deletes anything with more than one "Fw:" in the subject line. If you just blindly forward crap to me without taking the time to make it look nice it probably isn't worth reading.

Hotmail is evil. I only use it as an e-mail address I can get all my spam sent to when I need to enter a valid e-mail addy for something and I think the addy may get sold to spammers. It's also interesting to note that even though you can supposedly set filters to block your mail you can't set the ones that would do the most good, particularly ones on Aliases (as opposed to the actual e-mail address) Hotmail really encourages spammers I think.

I don't have rules for that, but I end up doing it manually anyway. My parents still bother to actually read the useless forwards, but I told them not to pass that $#!7 on (and "enforced" the rule by not teaching them how to use the multiple-recipient features of Outlook ;)) because none of it is true (especially the little boy with cancer messages and the forward this joke 10 times to see the answer messages).

Agreed. I hate hotmail. :evil:
