I fell inexplicably to mid 1400 overnight on Chess.com. The head of their customer service denies any cheating. I change to Lichess and rank 1838 ELO a week later for the same blitz game. Lichess scores are about 200 points more generous, which matches what Chess.com's staff told me: that I play at about 1600 ELO by their standards. That I lost 200 points overnight points to cheating within Chess.com. At no establishment, online or physical business, have I experienced rudeness and arrogance like that exhibited by Chess.com's head of customer service. He publishes criticisms not only of your games but of you personally. The CEO emailed him and told him to be nicer, and shortly thereafter implemented a member feedback rating of staff online behavior. One of my last games on Chess.com featured a member whose tactics measured at ELO 2014 yet the sandbagger was hiding inside blitz 1400 ELO with artificially low fake blitz rating, a problem explicitly confirmed by Chess.com's technical service as a epidemic in their website.
