@freemo Can you see which instances are blocked? And how do they do it?
@mundauf Yup its defined here in the source. Trivial to edit:
@mundauf Its a recent rather large debate across the fediverse.
Tusky had never previously blocked any instances as far as I know. Gab however recently decided they were going to migrate over to mastodon (or a fork of it). the intance that is up is experimental and very few people on it. In response for the first time the Tusky dev decided to add in a hard block.
The result is the whole mastodon community seems to be debating the issue and morality of that move.
