The funny thing is that... let's say you lose a few games to a cheater. Sure, that sucks, but you don't know they're cheating, and you keep playing games.
The way the rating system works is you'll gain your points back naturally... so why is it useful for chess.com to give you rating points? Because the overall effect of many cheaters being banned is they permanently remove rating points from the pool, which has the overall effect of decreasing everyone's rating.
By giving you points after losing to a cheater, your duty (so to speak) is to lose those extra points back to everyone else. Sort of like getting a shot at the hospital. Those extra points will help the whole body, you just happen to be the part of the arm chess.com is sticking the needle into haha
I just realized something funny about this.
