This question already has an answer here:
A few hours ago, I had 418 reputation on StackOverflow. Currently, my profile shows 371 reputation, meaning I lost 47 reputation (I don't mind it).
Surprisingly, there are no notifications in my profile like "User was removed" or anything at all.
I got no downvotes in the last couple of hours. No questions or answers were deleted. My profile is as it was before. What might be the reason?
