Chess.com Ratings are a JOKE

You obviously are not reading your own posts then.

This site is about 800 points overrated compared to real ratings

Your explanation for your subjective experience only makes since if your 1200 ("little timmies") pool of players /never plays anyone in the higher rating pool/.   Otherwise, as a cohort the lower ratings would all increase together, and the higher ratings would all decrease.  

It also only makes sense if every player who is improving /has exactly the same rate of improvement/.   Otherwise, players in the lower rated pool would improve at different rates, therefore have a distribution of expected match outcomes over all pairings, as usual, and their ratings would adjust according to that in the usual way.

Both of these or clearly not true.
