So I posted a hand-made riddle on Puzzling yesterday (for which I got 20 upvotes:)).
Anyways, today, I come back to see a very increased amount of reputation on ALL of my stack exchange accounts.
For example, in this picture, you can see the (very fast) increased amount of reputation, even though I have only 3 questions (one with -1). here is the same thing...
So is it because one of my questions on a different stack exchange site that increase my reputation on all of my accounts, or is it a bug?
