Don't you think you should check with theymos first before taking things into your own hands and going renegade?
This is why you need to join us on IRC.
I have previously only really trashed threads if they explicitly state that they're hacked or cracked etc but it's not going to do any good if there's no consistency and only you or a couple of staff are trashing threads by newbies whilst everyone else's are left alone.
I have only removed those that seemed like they were illegal (e.g. "they're hacked accounts"; "don't change password"). Besides, it is pretty obvious if someone is selling yearly subscriptions for a few dollars. If it was legal, they'd be rich by now.
