Why did my reputation go down 100 points?

$\begingroup$ Could you say where you see your reputation displayed as 100 points? For example, if I look here, I see 699 reputation points next to your name. What is your setting regarding hiding reputation? See here: Reputation and badges are no longer visible next to the users' names. $\endgroup$

$\begingroup$ My bad, I misread this - I thought that you are saying that it went down to 100 points. @EmilJeřábek I hope that the OP will give more details - but one thing that can be easily checked is that the reputation graph in the network profile shows 799 points. (But I do not know how often it is updated.) Here is also a snapshot from March - but that was a long time ago. $\endgroup$

$\begingroup$ Oh, I missed that. At least when I view it on a phone, the graph is so thoroughly mislabelled that it appeared to show something in the vicinity of 700 to me. $\endgroup$

$\begingroup$ Some ways how to lose 100 points in one go are: a user who upvoted 10 of your posts has their account removed; you give out a bounty; one of your posts is automatically deleted by spam flags. But all of these should properly show up in your reputation history, so I don’t know what may have happened. It’s not really possible for outsiders to investigate this; if you do not find the answer yourself, try to ask SE developers using the “Contact” link at the bottom of any page. $\endgroup$

$\begingroup$ Check whether you have deleted questions or deleted answers, and whether they're deleted by Community bot. $\endgroup$

$\begingroup$ @AndrewT. I did not have deleted questions or answers. And it still does not explain why my plot shows 100 points more than my number. $\endgroup$

$\begingroup$ Hmm, the usual case for the discrepancy that I know is due to the post getting nuked with the red flag. What did you see from the reputation audit? mathoverflow.net/reputation $\endgroup$
