if a user is bothering you in any way (harassment, spam, etc), you
should contact a moderator so they can take the appropriate steps
to ensure that both parties involved are properly taken care of and
hopefully come out of the situation with a pleasant result
sometimes things are just a misunderstanding, and talking it out
and coming to an understanding would be better than just ignoring
anyways, and there is a report button as well :)
I also don't support this. What if the user wants to apologize? If
you don't like the message from the user, contact a
Moderator/report him. If he doesn't stop he gets banned and you
won't get any messages anyway anymore.
