Zev,
That's a bot that's plauging the site right now. It lifts a paragraph of similar context (this case a comon as3x blurb form HH) and posts it as a new user -- the bot's payload is in the signiture, the linked store.
It's been reported and will be delt with.
When you see it aagain *DO NOT* click the link -- it only rewards the bot, at best, and there's a chance the site could be a malware trap -- the very good traps, you wouldn't know they did anything.
Either way RCTOPHOBBY will never get my business. Ever.
