Well, I'm still playing 10+0, as my connect is bad. But last month I only played several games, as there are a lot of cheaters. There is about a half of a month I never played a game, but my rate was up, about 100 points. As these cheaters were found and banned by chess.com, chess.com backed these points to me.
I almost cannot bear anymore. I heard that the problem about cheater is forbidden in the forum so I would not complain more. So, maybe Blitz is good, as it is harder to cheat in blitz, you can fully enjoy a true game.
But the 10/0 from blitz thing bugs me too. My blitz rating is 200 lower then my rapid and I am not able to close the gap. And believe me, I try :-)
