1) The 'other forum' requires a User Name and Password to make posts and follow-ups. Obviously, this one doesn't.
2) The Fix-it For-em BBS does track enough information to 'trace' those posts that, ... well, need to be traced. This 'upgraded' BBS, along w/the upgraded servers and Operating System, allow BV.com to do a much, MUCH better job of tracking its visitors. You remember the Imposter, eh? If there's a next time, BV.com can track the IP address back to the ISP provider, find out 'who' acquired that IP address based on when the post was made, and prosecute. Believe it or not, they've done it once already, and successfully.
Those folks 'in the know' already know that it's in their best interest to 'play nice' in other people's sandbox.
