@ajroach42@angiebaby@newellijaytv This should scale with "number of instances occupied by followers" as I assume (hope?!) that the previews are generated per-instance.
Unfortunately the post doesn't share the number of servers hitting them (surely it's not 37000+ instances?)
Sites that can't handle this number of requests could presumably take some steps themselves (e.g. "slow down requests from Mastodon instances"). What do they expect "mastodon" to do here, exactly?
