Only once, I told someone his stupid request in the help section for a private/unobtainable/fail-binned add-on was stupid.
Can't understand how that didn't deserve to be dismissed, but I guess its nicer when we live in a world where stupid people get infinite opportunities to be given assistance. And I guess it made me better as an individual, now I use sarcasm to be dismissive instead of just saying "nope".
Other than that, anyone who has an alt account has something wrong with them, this forum is fairly lenient as far as the usual jav that would get someone banned. If your account somehow has managed to be perma-banned more than 5 times, then color me impressed.
