I don't trust Chess.com I think the site is very unsafe technically. Either unknowingly or dilebarately because the site is desperately trying to make money from members. Probably all who are complaining are non members and were never members.
Alot of spooky stuff has happened to me on Chess.com and I recommend running Chess.com on a virtual machine.
I have problems where my opponent's time is running, and I wait and wait and wait, only to loose on time because my move was not registered. It clearly showed that my move was played, otherwise why is my opponent's time now running.
My connection just suddenly looses, however I am using a lan connection, which never disconnects. The only time I face disconnection problems is on, you guessed it, Chess.com!
Other even more spooky things has happened to me on Chess.com but people might call me paranoid if I say, so I will just end by saying that their are security issues on Chess.com. I know they are trying to earn money and nothing is wrong with weeding out non members. But doing devious practices to make money is not moral and probably illegal. If you don't want us on your site just disallow us.
If Chess.com is not the problem then obviously their site has major security holes, and unscrupulous persons could be using the site to do illegal and dangerous to our health things.
Recently there has been unexpected load on the Live server process and staff have been looking into some limits they are hitting. I haven't seen an update but I don't see all the posts
