Why did my reputation go down by around 300 points?
I had around 1463 reputation one day (just a few days ago), and when I came the next day on Stack Overflow I had only 1144 reputation.
Where did all that reputation go?

Anyway, if you find that your reputation has changed overnight, it might be because we now check for, and remove, any suspicious upvote or downvote patterns.
This is exactly what happened in your case. Note that this doesn't necessarily mean that you did anything suspicious – maybe you have a fan that votes you up a lot.
