I have recently noticed that I lose some 2-10 reputation points every day (been going on for about a week). I disregarded it because it was a very small amount and I used to think that my edits would have been overwritten (I don't think this happens though). Today, I lost around 20.
Worried by this, I checked my reputation notifications – no sign of downvotes/negative reputations here. Then, I checked my reputation history – looking for reputation loss due to deletion of users' accounts – found none.
So here I am, looking for some reason. Why does this happen (mysteriously)? Is it because the community has decided to penalize me for any ill behavior? Or is there a different reason?
