Being blocked on one out of hundreds of platforms is hardly equivalent to being killed, more like being banned from a mall after defecating on a bench. Being blocked by an individual user is an equivalent of stern stare, disapproving shake of a head and never getting any party invitations again. All justifiable for intentional trolling.
As I mentioned in the other comment, I am not equating the two, I am merely stating the case that punishments that are final/irreversible are bad news.
Also, in the comment you responded to, I had already stated that I am specifically _not_ referring to individual-to-individual interactions.
As for your mall analogy, maybe if said mall is the one that 1/6 of the human population shops at, the nearest competing malls only have 1/20th of the people/stores/stuff and there's only 1-2 competing malls where the shopkeepers speak the same language as you.
Actually, after thinking about it, I do agree with you on platform-wide permabans, they just encourage trolls to find ways to create throw away accounts.
Timed bans (with exponential increase for reoffenders) or permabans with a process to lift it are better. Then trolls who can be beaten into submission would be, those who can't will get effectively permabanned eventually and public places can be kept one step away from being toxic cesspools they would otherwise turn into.
