For my particular niche (illustration) it has a way better concentration of active (and also importantly) high quality actual working professional artists on it than mastodon.
The art scene on mastodon is pretty meh and the largest art centric instance is run by unstable authoritarians that are some of the biggest sources of drama on mastodon.
Just like how many people stopped being supportive of labor unions, a lot of dummies out there have this misplaced belief that as soon as any problem goes away, we no longer need to uphold the things that solved those problems in the first place.
Of course that’s not at all how the world works. Bad actors are constantly looking for gaps in our defenses. They’re never going to fully go away because there is an ever present 25-30% of humanity that frankly sucks.
It requires a continuous collective effort to stave these despicable motherfuckers off.
