Not clear if it plays an actual role in federation, depending on if the fediseer whitelist API is widely used
Not really, instance defederation is still a manual process through Lemmy's API. It's useful for sharing info about instances and I have used it to defed from some instances (mostly CSAM). The main thing you need be guaranteed for is so you can be on lemmy-federate.com. Irrc, Piefed also NIH'ed their own 'trusted instance' thing.
Though this again raises the question of our status w.r.t to Lemmy.world being our sole Guarantor.
I don't think you can have more than one Guarantor, it's a limit in Fediseer itself.
I wonder if we could have multiple daddies to be sub to if one of them brings out the nipple clamps 🤔
We are strictly interested in sugar daddies, if you can find someone who can also afford us, we'll happy put on whatever clamps, ties, or suits they want.
