If a self-voted post or comment is making more that you feel appropriate - flag. Don't complain.
I'll downvote and I'll complain. Complaining is the act of making others aware of a problem. I don't believe the existing ruleset is sufficient to deal with self voting. I don't want to remove the possibility to self vote, but it needs to be easier and less costly for stake to counter stake.
(Costly in terms of human attention and network resources).
