The outcome of violating the GPL is license termination: you cannot distribute it any more. I don't think there has ever been a case of enforced further distribution or disclosure.
My main point was that to my knowledge there has never been a case of forced further distribution.
About termination, what you mention is kind of stopping further violation of the terms and maybe compensation for the past violations. What I wanted to mention (but wasn't at all clear about) is that after termination, you cannot even distribute if you intend to abide by the terms unless you are forgiven by the copyright holder. (In the case of the GPL version 3 there is some grace period during which for the first violation, if you abide within that period, you are explicitly permitted to resume distribution under the license terms.)
