I decided to give Mastodon another shot here recently, I found exactly one promising leftist instance, mastodon.lol. Bills itself as an "LGBT-friendly antifascist mastodon instance"
I watched another user get banned for saying that Azov were neonazis and I got banned for sticking up for them, then as part of his 240V power trip the admin posted a pity thread where he claimed we called him literally Hitler.
The only other leftist instance I saw welcomed all socialists except "authoritarians" so I assume it's either a socdem or sectarian anarchist instance.
TL;DR - Mastodon hasn't changed at all, it's still ran by power-tripping micro tyrants
As much as I love metal as a genre, it's a community with a lot of chuds in it.
I also didn't pick up on the on the twitter clone because I've been drinking with my neighbors.
No worries lol, you're out there touching grass and I'm in here bitching about tiny internet forums on other tiny internet forums
Addendum:
I'm drunk in a bar full of plastic paddy's and fighting the urge to school everyone on irish history.
I'm Scottish.
