How can I tell which game was against a cheater?

Chess.com sent me a message saying they "detected that one or more of [my] recent opponents has violated our Fair Play Policy." and they gave me a higher rating (+7) as compensation for playing against a cheater.

I was wondering, is there a way to tell which of my ~270 games was against a cheater? I would be very curious to go through it and see if I remembered anything feeling suspicious.

In your game history, there will be a red symbol next to their name.

Sadly there is no convenient way of telling which games. A link to the game would be appreciated

Did you say that to make a advertisement for Cheetos 

how the hell is it possible to cheat in bullet
