Add the ability to ignore users
There's a user, a contractor working at our company, who's decided to prove to me that on-line cooperation is not functioning. He's already caused me to be banned for a week and I fear that he'll keep doing stuff to make my life sad.
Is there a way to delete or ban him? Of course, he can register again but it takes a while before he has reputation high enough to start messing with me again.
Even better solution would be to ban him from seeing me and my posts, so he can bother someone else or none at all.
EDIT:
I'm shocked at the negativity. In fact, he did nothing of the kind you're assuming. In fact, he UPVOTED my posts so I got canned for inappropriate reputation manipulation.
