They need to do away with vacation. You need to play the game or get off the site. It is not fair to let your opponent hang around for God knows how long…
my opponent is still on vacation.

Postponing games when going on vacation is not invented by chess.com. It is pretty much a universal rule of correspondence/daily chess.
You kids apparently cannot understand that some people have things and responsibilities in their lives outside of chess, and those things can sometimes make it impossible to keep playing without breaks. Once you grow up, you'll understand.
And if you believe someone is abusing it, you can report them.

like 95 percent of people have jobs. no matter how grown up you are or what you do for a living the concept that someones doesn't have time to make one move a day is nonsense to me bathroom breaks lunch breaks. The concept that you can take 90 days with out making a move is rubbish
