OR...
A handful of users out of 60,000 online at a given time don't understand how the internet works, and blame momentary loss of connection on hacking. If someone can prove that all of their *time-dependent transactions* online are working at the exact moment they lose clock time at chess.com (not just some other browser tabs that can retry the connections without visible effects anyway), then you can *start* to make a case,
You tell me the most likely cause.
Just for the record - i have never lost connection (to chess.com or any other site). I have rock solid internet connection from my cable company that has 100% uptime / connection in nearly 2 decades. My internet connection has gone down less than 5 times in 2 decades. So, rule out connection issues (true for most USA players with cable modem). I know enough about computer networks to understand what is lag and what my lag is etc. Lag is also not a issue.
In order to hack timer, geeks do not have to go into the server (which is hard) - they can hack the javascript (or whatever else chess.com is using) and gain into loop holes.
Lol. You actually think your cable modem has never had packet loss or dropped connection in 2 decades? As someone who worked on the backend systems at ISPs for 11 years...you need a serious reality check. Plus, you're on cable, which is a shared network parceling out bandwidth to other users, so there is absolutely no way you can say that your connection has not faltered due to peak periods in your area, unless you are actually pinging/monitoring and logging your packet loss 24x7.
Javascript "loopholes" would only work if chess.com were to allow the client to "argue" with the server about how much time has elapsed. A hacker might be able to screw up a live game in its entirety by spoofing something that confuses the server, but they would not be able to make your clock and only your clock lose time, unless the devs are chess.com are complete knuckleheads, and I don't think that is the case.

Alright, now I've clicked b*tch and it's a monday. (lips taut)
