There’s a list on the Mbin’s website, I’m surprised it wasn’t mentioned yet
I can recommend these instances:
- fedia.io (It’s the biggest one, so it would be better to avoid for the decentralization)
- kbin.earth
- thebrainbit.org
The later two are run by mbin devs so they should be pretty good
Additionaly there’s !AskMbin@fedia.io magazine, so you can ask questions there instead.
It’s not available in my country 😪
