If the domain was registered a couple years ago yes you would get tonns of spam, now you have to enter the text on a picture to get the whois info. This does help to limit it.
I have several domains, I am a designer and host and design a number of sites, and what I have found about spam is this.
1. You get it when you enter your email address anywhere online that a spider can serach.
spamme@spamsucks.com is going to put your address in the lists. but spamme at spamsucks dot com or some other way that a person can get teh 'code' but a bot won't leaves you better off.
2. Never ask to remove yourself from a list, this just confirms that they got a real addy and send more.
3. Never publish the address on the web site in html. If you want to put your addy there then make a .gif file of the text in the same font and color.
4. Never use the mailto: link as this is serachable by spiders as well.
5. Use a contact form that hides the email address in the code so that bots can't get it.
Try to avoid using
webmaster@yourdomain.com or info/sales/owner@yourdomain.com These are just begging to get spammed.
I get ten times the spam on my webmaster and info accounts than I do on my regular account, all at the same published domain.
I use the privacy feature if i don't want the owener of the domain known. For example one of my clients is an exotic dancer. For safety reasons she does not want her info available to the public, and she owns the domain. It is good for this. BTW she gets NO spam and has never put her email address online in anyform, and the domain is registered to this name. She also does no shopping or in anyway gives out the email, accept on business cards, and replys to her contact form.
