I don’t think it is fair to characterize their position as “let these guys run rampant”. The fact someone points out something that is unacceptable, does not automatically make them responsible for downstream effects and the solutions to these problems.
While I wholeheartedly agree these people (the online abusers) should be dealth with and the behaviour should have consequences.
ISPs and other commercial entities should either: curate the content and be liable for the content… or stfu and leave it to a government entity.
I favor the latter, realizing that this would require the entity to have proper funding.
