But idk what the reality of having a community like that would be
Interesting question since there’s no precedent.
If a copyright troll were to go after links on the Fediverse, what would they do. I guess they’d have to target the owner of the instance that hosts the community. If you set up an instance on a VPS that doesn’t care, like those that offer seedboxes and debrid services I guess they’d just get ignored. I suppose they could go after other instances and force them to block the offending instance, I don’t know.
To set up a community like that, probably best on its own instance using a copyright resistant VPS. Would keep it insulated. It could get blocked by other instances, but should be possible to create local a sign-in for direct access.
