It went on for page after page, and countless threads were created about the simplest of things, because he is either clueless and unable to follow the answers he gets, or is a troll who stay within the TOS for the site he is trolling.
He goes/has gone under the names:
DexterMcCoy, BillyMayo, VanCastillo, Walters, and a few others. He causes trouble wherever he goes, because the general membership can see through his posts and eventually ID him for who he is, but until he falls foul of the site's TOS, he doesn't get banned. The Mods/Admin have a difficult time because it takes a while to trip him up and make him fall foul of the rules.
I read all of his threads on AAC and got sick of seeing well-intentioned individuals getting sucked in and replying to his BS. There's always someone new, who doesn't know him, trying to help out and it seems he gets his kicks from taking the P, the I and the double S out of those trying to help.
I sort of 'spammed' one of his last threads on AAC, by asking multiple questions about the minutest details of his OP, asked him to post the proprietary schematics he eventually got banned for, and pretty much gave him as much as he gave out to the rest of the forum by asking him multiple pointless questions about information very loosely related to his replies. The next day, all of my posts were removed and I got a PM warning me to stay out of his threads, otherwise I would get a ban. The day after that, he was banned.
Regards.
