Blocking a user and removing content from a platform should be relatively easy and fast which should prevent organized crimes. Sueing someone afterwords takes way more resources and time.

But a platform can remove content without getting sued. Why sue them too? Because if you don’t sue their asses they don’t care.

Of course moderation takes time and can’t be perfect and this should be considered when suing the platform owners. And yes this could help the assholes, but I think you can report such behavior to the fbi or someone.
