The game ratings are just quick estimates. Anyone who plays a good game will get a game rating higher than their playing rating.
At any rate, I see two accounts closed for cheating in your January games. It seems clear they are still looking at the games.
I don't know why you aren't getting email notifications.

I have just lost a game to an opponent with 1992 rating who played (according to your board analysis) like one with 2300 rating. My conclusion - you stopped your battle against cheaters! I used to receive messages about someone cheating while playing with me, monthly. Now I haven't been receiving any for a long time.
