If you offered most people free streaming for a $37 USB stick but directly told them it would be faking ad clicks when the TV is off, would any of them really care?
Maybe they wouldn't care about the ads but the residential proxy is another story. I'm sure lots of problematic stuff goes through that and you take the risk of being associated with it.
No, and that's is the root of the problem. The buyer is happy and so is the seller. They don't care to understand what they're allowing and everyone is allowing it to happen.
