Does the gmodstore actually ban people?

Does the gmodstore ban people who leak scripts, or people who use them, or both?
I'm geniunely concerned if my DarkRP server will get sued, or if my steam account will be banned from the gmodstore. I guess technically there's no proof, but doesn't mean a person could be banned or attacked out of spite from someone who's pissed about their script being leaked.

I never understood why people charge $15-20 for a lua plugin addon for a game that is 15+ years old.
