# reputation points - how are they determined and by whom?

How and by whom are reputation points given? On May 30 I answered a post and it was rated +30. On May 31 it was rated +25 (I don't know if that was a replacement or an addition). On June 2 I received a rating of -10. I received no explanation of any of this. What is going on?

• A full analysis on reputation is here - meta.stackexchange.com/questions/7237/how-does-reputation-work. Basically reputation is only given in preset amounts, e.g. $+10$ for an upvote, but it of course stacks, so $5$ upvotes would total to $50$ rep gained for example Jun 2 '19 at 23:14
• When you are displaying your reputation tab, make sure that the checkbox for "show removed posts" is checked. Jun 2 '19 at 23:16
• My opinion is that it is many times somewhat whimsical. I've seen well-thought-out posts that obviously involved a lot of effort and provided detailed, accurate analysis get 1 vote, and I've seen abjectly trivial answers (from members with 200k+ points) get 10x that. It's like facebook likes. You just can't take them too seriously. Jun 18 '19 at 17:07
