I think I first mentioned the T-shirts after the Børken Source episode, after some of the things being said sounded like t-shirt slogans.
I haven't banned any /[Vv]a*/ usernames, and "Vaskerville" doesn't appear to be banned. But then it doesn't show any activity since 2015, and I saw the post only a few days ago. Mind you, I can't find that thread either. The site db is going wacky at the moment and I hope it's sorted soon.
But I found [thread=10275364]the thread where you actually had the discussion[/thread]. Okay piersk suggested it first as an official site thing, I recalled the Broken Source thing, and you said you'd make some from second-hand shirts and spraypaint if customers included "cash, return email addresss, SSN and mothers maiden name within the body of your email."
Not banworthy. Especially twelve years later.
