It's a little known fact that we actually previously had an NSFW piefed instance for a week or two to do testing. Some of the features that were included to help instances like that were the disclaimer screen that comes up before any content page loads (this site has NSFW content...etc.). Also, I know some code was added to make some common NSFW hosting sites work better (as an example, there is some special code to deal with redgifs embeds).

The last thing that comes to mind is to allow admins to specify countries for which NSFW content is blocked (based on IP address). This was added in response to admins wanting to deal with content restrictions like the UK have and are sadly becoming more common across the globe.

No idea about piefed but the worst part for me about this instance swap is that I have to go visit dozens of different communities and view the banners to block them, because Lemmy doesn't have a dropdown for that like it has for "block user". It applies blur to the posts, but unfortunately not banners, so I either have to block the entire instance or visit each community to block it.

I don't need to see some of the stuff people enjoy to know that it is not for me. Plus the sheer quantity of possible combinations for anal gape creampie yiff hentai is overwhelming, before even considering further granularity by anime franchise or whatever else.

I was considering changing instance anyway so maybe this is just convenient timing.
