Given that many creators are already violating copyright law by either porting existing characters from IP they don't have license for or are creating likenesses of celebrities that they did not get permission to do, they're already on shaky ground.
If they were to spread viruses deliberately, that's a cybercrime in the US and can be charged up a felony and also opens them up to civil lawsuits. Even if all it does is identify the user, that still falls under the purview of US cybercrime laws.
That's just the US, mind. I know plenty are not in the US, but plenty of other countries have laws for cybercrime and most of them wouldn't protect someone making sex models of celebrities or using IP they don't have rights to.
