As I said earlier, it is listed MANY times on the site Brdad mentioned - all spam email addresses - and it is an ISP in Amsterdam, Holland that we have had many fake "new members" from.
It seems it would be great if anyone logging in from a known spammer IP is restricted from posting or maybe joining until a webmaster allows it. Those people would have to send a message asking to join.
Of course, that's probably not easily implemented.
Regardless, the list is a good tool to use for reference.
I agree, many of the sites I frequent now require you to sign up and you cannot post until it is approved by the webmaster. If this sort of stuff continues to be a problem then that is a possibility.
Oh, and thanks for the informative post way back at the beginning!
on my site you have to click on a verifcation email for verifcation b4 you can post anything
