And they never will so give it up. Sure, there may be the odd person that recognizes your name, but so what? Making an "epic" thread won't get you recognized, even if the thread does.
Nobody will remember you as a spammer either, they won't remember you as the meme whore, and they won't remember you as the great poster with great grammar. Some people may remember one or two threads upon hearing your name, if you're REALLY lucky.
If you're on the BBS trying to obtain a level of famous I suggest you stop now.
Posting is about trying to make a witty original comment once in a while, or help somebody out. It's not about bitching at the Russian guy who can't formulate sentences properly. It's not about being somebody that only ever posts "lol" "fail" "barrel roll" and "grab his cock".
