@alexproe @Eetschrijver there are MANY different types of instances.
You just happen to be on an instance that blocks those other types.
Instance admins have to always be on the lookout for new instances that go against their instances rules so they can block them.
That's why it's always good to report rule-breaking posts whenever you come across them. Mastodon doesn't have automated moderation. If an admin doesn't see it, it can't be moderated.
