This is my first post on meta, so I'm not sure if it's on-topic. Feel free to tell me if I have to delete it.
I'm feeling a bit upset, because my two top-voted posts (my top-voted question and top-voted answer) have just recieved a downvote each, with no explanation at all.
I believe it's some kind of I-just-wanna-annoy move, and not that the downovter really thinks the posts deserve it. Otherwise, why do it without revealing his/her identity or explaining the reason? Also, the fact that it was not one but two downvotes in less than a minute makes me suspicious.
The voting system is completely anonymous, right? Because, if it wasn't, maybe it would be possible to keep track of these cases and communicate with the users that to tell them they should explain the downvotes, or punish them in some sense if they were just trolling. Is this agains the community principles or something?
