"No cops allowed" in the TOS isn't enough to keep cops out; I'm sure pirate websites have tried this and failed.
But the fact that "No cops allowed" can't be the whole of your legal armour doesn't mean that it can't be part of it:

So Valve have empowered the producers of commercial cheats to flag innocent players as cheaters simply by hosting their DRM servers on the same physical box as another non-cheat related service that gamers are likely to use.

So i have to ask, suppose you purchased something locally snd the clerk gave you to much change, what would you do?
I think you'll find that most brick and mortar stores have a notice telling you to "check your change before leaving the counter as mistakes cannot be rectified later".
