I just created an account on ero.ani.social.

For new accounts by default, the setting “NSFW posts” is set to “Hide Completely”

ero.ani.social/user/settings/filters

That’s probably a piefed default.

This setting also hides NSFW /c’s as well as posts.

I think it’s safe to assume that anyone who is creating an account there knows what is up, and will want to start seeing NSFW content and communities immediately.

I’d recommend you change the default setting, with maybe a disclaimer for NSFW content on this server when creating the account.
