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.
An upside of the porn spam is that it linked me to what new instance to block before it became an issue. I don’t like blurring nsfw by default for artistic nudity or non-porn nsfw content, but I also don’t like my global feed to be half porn, so I find blocking the instance to be a good enough solution.
