no one used blockchain for this because:
1. it's slow, requires insane amount of storage, power and traffic
2. nobody wants non-transferable username for real

Compared to the infrastructure required to uniquely identify every human in order to stop them from registering lots of troll accounts, and implementing a fair and accountable law enforcement apparatus to make sure the rules are followed? The blockchain might be cheaper.

Which is the worse outcome -- you can't transfer your username (but you can register a new one for a fee), or trolls and squatters can trash the system?
No problems with spammers or trolls at all. And that's literally my experience with 20+ homeservers that I configured
Again, nobody wants unique permanent ID per human.
PS: regarding "a new one for fee" - I hate services that work this way (hello, Blizzard), IMO.
