Those wouldn't be downvote bots then. Obviously, there are ppl. here who were trying to help with constructive critisms. Voting I believe from what I've just read in the FAQ and other posts is a feedback mechanism. It isn't to feed one's ego. Although, I'm sure that happens here as well (yes, that's only a guess). From other posts on this topic - the downvoting of that post was warrented or warrented by opinion. No bots were responsible. It sounds like an unfortunate incident. In the future, I think it should be remembered why the voting is here in the first place.
