Apologies if this isn't the right place to answer this question, but I recently ran into the following issue, and wasn't sure how exactly to handle it.
On this questionthis question, I posted an answer, and returned about 10 minutes later to find that someone (vehomzzzvehomzzz in particular), had copied part of my answer and pasted it into a new answer (now deleted) in such a way that it didn't fit at all with his answer and was just a blatant grab. (e.g. the answer ended in "for instance:" ). I down-voted his answer and left a comment along the lines of "if you're going to copy/paste from me, at least edit it to make it cohesive". There was at least one other downvote later.
Since then, vehomzzz has deleted his answer and left the following comment on mine:
@Dusty im on to you now - I will downvote all of your answers/questions
and he did indeed go through and downvote many of my answers out of a sense of retribution. While this only cost me about 20 rep, it seems like incredibly anti-social behavior, and on a site where the community is so important, I'm hoping that there is some relief from this sort of behavior.
So I guess my question is, what is the best way to deal with this sort of thing? Is there some sort of moderator relief? Should I just accept it's going to happen and deal with the minimal rep loss? Other suggestions? I hate unexplained downvotes, but now I certainly see why they would be advantageous.
Update: his comment is now @Dusty -- it's ON!
Lovely.
