Recently I see a lot of cheaters and chess.com is nothing doing against them. I describe You how the game looks when You are playing against a cheater.
1. At the beginning of the game you will receive information about user disconnection, and If he doesn't come back Yo will win, but they always come. It's the time, when the plugin for chrome is connection to the user session, so that's the reason why you see the disconnection notification.
2. If at the beginning of the game disconnection notification didn't appear then in about 7-9 move you will see a long time without move and after this your opponent will make the best move - the progress bar of analysis will fly to the moon, ideal move and after this you will see fast moves in max 5 seconds or will play with you and pretend that he/she is "thinking" which move is the best.
3. Every time plays one of the first 1-4 so he/she will not get in the end accuracy more then 92%, because such action could trigger anty cheats.
Chess.com is doing nothing against such action of cheaters, but banning my other accounts, because I broke the holy law of chess.com of not having more then 2 accounts was easy for You, but remember that I caught cheaters and made them get banned faster, because I could report them from my many accounts and a weapon against them and I wasn't transferring points from one account to another.
Please do something with it. I have really enough of such cheaters! On 10 games 7 cheaters - that same scenario - a lot of people from South America, USA, India, Spain.
