I know that if someone upvotes my question I get 5 points, if they like my answer 10 points, and if they get removed I'd loose 5 or 10 points this way.
I am puzzled though because I just found this on my Stack Overflow account:
-4 19 mins ago removed User was removed
how can you lose 4 points? I.e. for what? I'm assuming that this is perhaps 2 × 2pts?
I get 2 points if I accept someone's answer, does this mean the user who provided two good answers to two separate questions to me was removed and I lost these points, or is there another explanation?
I looked here http://meta.stackoverflow.com/faq#reputation and it also mentioned +2 points for edits, but I don't recall getting points for editing, and would this mean I edited posts by the same user twice?
Just curious, still trying to understand the whole rep system.
EDIT: Just to be clear, I lost 4 points total. I assume — perhaps incorrectly — that this might be due to 2 × 2 points since I couldn't think of another way getting to 4 points.
(I don't mind the loss of 4 points, I just want to understand.)
Thanks everyone, it must have been the residual points from reaching the daily cap as I was rather active on SO over the summer so I consider the mystery solved (and now also aware of other ways this could have happended). Everyone got an upvote for their help.
