How should we treat users on bugzilla?

[Dan Kegel]

I've been seeing a lot of bugs closed as INVALID
when a poor user didn't file the bug perfectly.
IMHO this leads to Wine having a user-hostile reputation.

Case in point:
http://bugs.winehq.org/show_bug.cgi?id=11625

What can we do to reduce this kind of behavior?
Maybe we should have a "three warnings" sort of
policy.  If somebody continues to be rude to users
after being asked twice not to, we should consider
taking away their Bugzilla privileges for a while.
Sure, that would hurt our productivity, but it might
be better to do that than to alienate our users.

What do other people think?
