How about this solution:
Until someone has at least 100 posts, they cannot post from AOL.
Once they get over 100, they can start using any ISP. That will filter out the trolls because it would be more impossible to start new accoutns with AOL. At the same time, it would allow old time AT users to use AOL if they switch ISPs for whatever reason.
Seems like a good comrimise.

This has been suggested, before. Sorry. Our software does not allow such distinctions.
