I just lost 100 reputation

$$anonymous$$oved to the meta space.

Are you sure you did not downvote others? Downvoting cost some of your own karma / reputation, though not that much. Keep in $$anonymous$$d that votes on all posts count, so votes on comments do also increase / decrease your karma. Also if the accepted answer is taken away from your answer you also loose those 15rp points again.

Unfortunately we can't see how the reputation changed. This was way more transparent with the old stack exchange engine. When UA switched to Qato the quality of the site went downhill drastically ^^. Though we have to live with it.

Note if you see spam, don't downvote such posts, just report them and maybe send it to the moderation queue. Downvoting cost 2 rep. Also rewarding another user manually (reward user button) will transfer some of your karme to that other user.

I'Ve just upvoted some of your answers / comments ^^. You're closer to 2k again :)
