They should also take away the ability to delete posts.

Too many people want to try to save face and delete their own posts to try to make themselves look good in a week.

"You can't say I said that, I deleted that post, so you can't prove I said that"

"I didn't intent to defame you, I'm sorry you thought that way, so I'm going to delete any evidence as to otherwise."

Actually, if SE actually gets hard on trolls again, it might make this forum somewhat reasonable again.
