I had problems with Vanguard playing LOL. Riot wanted to ban my account because according to their anti-cheating system I was abandoning many games and rejecting many others when the truth is that my internet connection makes the game slow to react.
In the end I managed to recover my main account but I was forced to create an alternate account to prevent losing my effort and time invested in the game.
That's horrible 😭
They tried punishing you for something out of your control.
I was also temporarily suspended from Overwatch 2 because my hard drive is too slow to load into matches. Using it on the SSD helped.
