I’m sure the audience will find it anyway without spamming the entire Fediverse with your porn preferences. Announce it on your nsfw instance and it will be sufficient.
Edit; oh boy, the gooners sure are taking this personally. Chill nobody is taking your porn away but also nobody cares about your little porn kingdom.
Edit 2; it seems that there has been a cleanup and the admin at that porn instance is working on it too.
Final edit: Now I know what hell it must be like to be a teacher with an unruly crowd of horny teenagers that can’t think beyond their genitals. Oh, well.
If I interpret this comment and this comment correctly, this may be a feature of PieFed that automatically (or with a checkbox?) announces new communities to this one, so the people who are doing this might not be completely aware that this is what they are doing and might end up not reading this post.
Multiple different accounts and their posts are all formatted exactly the same, so this does seem to be the case.
This is probably something that the instance admins can change.
Edit: It seems like they’re looking into it.

That was my interpretation as well.
