@cassidyclown@JAJAX There's much more users on the network than accounts, and no instance provides full list of deactivated users anywhere except maybe admin-only panels. It just isn't feasible. FYI, if API of Mastodon instance isn't locked, one can check if you're suspended on /api/v1/accounts/lookup?acct=usernames instance.tld
@mint@cassidyclown What I'm thinking isn't a tool that keeps a running database, but which only checks a bunch of mastodon instances to see if your account is suspended there. It wouldn't check unless you searched first.
It would also cross-reference instance blocks probably via FBA (does that have an API?) so it doesn't check where your instance is defederated.
@JAJAX@cassidyclown Interesting. I assume some very basic data about the user (at the very least, ActivityPub user URI) is still preserved, but nothing beyond that. Maybe it doesn't bother returning any data about the user if the instance is suspended.
