I expect this is already covered by existing regulations but the only enforcement avenue is a lawsuit. They know you won't sue them for $20.

I believe that’s why class action lawsuits can serve a purpose…

		In a class action they give $1 to every user they scammed $20 out of, and the lawyers charge $2 per user so you actually get nothing.
