@trwnh @tusooa i'm pretty sure this is what it was intended for, actually

LD signatures are pretty bad for 99% of cases; for Deletes, though, I'd think they're good personally. but for such cases, indeed, much much preferable (though they can't have "null IDs", but I understand what you tried to say there)

the issue is that they're still leaky on "who requested it" (something LD signatures aren't), but they're revocable and can be "plausibly denied" (whatever that really means, but many people very much care to not have signatures in their activities, which is fine)

i don't think mastodon's implementation is useful/good, however, but the concept itself is interesting
