I found one of the "open doors" for these a$$hats. A "new member" with a legitimate looking email address posted in the 'Trapping Hogs' sub-forum, and then they change their email address to one which clearly shows them to be Russian spammers. I kept one "new" member's profile up in an open tab for a few days and found the email changed to an obvious a$$hat, but, HAD originally been created with a legit looking one. I also found that a string of the new a$$hats all had been last seen in the "Trapping Hogs" section. I found a vague post (New Thread) in there, with an obvious batch of obscure hot-links and Russian email address. That door has been shut.
IF one of you find an odd post/thread which doesn't quite fit, please give me a heads-up to check it out.
Thanks.
