But you're threatening to and saying you require it as a precondition to allow a post to stand or risk deleting it. I'm saying I've seen plenty of claims from many sides here and never was there a threat that they provide proof or risk being removed. Granted, your statement threatening removal included compliance with the TOS, but you also required proof. Seems you should apply that requirement to those you agree with as well if you're going to throw that out there.

Edit: Perfect example--you're citing proof but you're not providing it. Where's your proof? I'm not doubting you; I'm just pointing out that you're not providing a link, or anything other than saying it was stated somewhere and the reader has only your word to go on. If you were providing proof you'd give us a link. So you're doing exactly what you're complaining Purple is guilty of. You're not providing proof.
