Well, to me the problem is being cheated (not a big deal anyway), not the game being deleted later.
Era of Chess Engines

The problem isn't not finding the accurate moves. It's that none of those people deserve to be 2800, and if this were to happen, the site would flood with cheaters, and games here would lose all credibility.
Chess is a game between two humans.
It's a level playing field.
Let's keep it that way.

Thank you. That was very inspiring. But about the temptations.
Hundreds of powerful chess engines are available. Chess.com usually closes the accounts which crossed the limits of 2000 ratings.
This is Chess Vs. Temptation Vs. Engine Mania

Adopt a sub-par cheat detection method otherwise useless games will be deleted soon?
What does that even mean?
You can detect a cheater from the moves, not just the rating.

Please share a few examples.
Here in the following games,

the move 7 .. g5! played by Topalov [[ Coment in the gameEveryone - including Magnus Carlsen - was caught off guard by this move ]] is also preferred by Houdini.
Since this era is the Era of Chess Engines,
I request chess.com to allow the members to play till they reach 2800+ rating. Close the accounts only if they cross above 2800. Otherwise we will have a trillions of useless chess games (such as repeated fool's mates, scholar's mates etc...) to be deleted soon. Though the players play fair games, using engines is also very tempting to find out the accuate moves.
Comments and suggestions are welcome.
Thanks
