Yes, that sounds like how it started from what I can nail down. I was hoping it wouldn't spread to ENWorld but here we are.
Maybe we can get one of the mods to post something on the front page, help get the word out that you guys actually have taste and would never sell a shirt like that. I heard about the shirt, but hadn't seen any attribution of who was selling it. Then again, I saw a thread titled that and had absolutely NO interest to read it. I was just disturbed that people would stoop so low.
