How does this prevent them from posting? If anything it makes our lives harder as we'd have to: check the unapproved post, tell them to fix it, keep checking it sporadically because people never @ us, wait for it to get reported again, and then either approve it OR go through the whole cycle again. I prefer the current system where some people read the stickies and we only have to message maybe 1/2 after a user reports their thread.
And how would it prevent ban evaders from selling the same accounts? There's no way we can possibly check whether an account has been offered for sale on Sythe previously.

If anything, I'm in favor of getting rid of rules instead of adding them; I want the site to provide the ability for people to sell things but not the necessity that they do so in "our way." Personally, I think things would work if we stopped posting on all those threads requiring pictures and whatnot. Ones without them just won't sell, and that's okay. They'll learn, update their threads with pictures, and things will work out fine in the end.
