this weekend i made a library for working with activitypub servers
@sungo rainbow tables 🤷♀️ a sufficiently motivated attacker finds a way, but i suspect such an attacker would find itself an easier way, too.
@sungo sorry, by "rainbow tables" i actually meant just "having put enough time into it." my bad, sorry.
@garbados thanks i hate it
@garbados I was thinking about this very same thing today as I was cleaning up my follows of dead instances
They should expire after a week or two of no contact.
@garbados dead fedi servers make up so much garbage in sidekiq
@adasauce i was astounded to learn there's no garbage collection process for dealing with them
@adasauce someone's gonna buy an obscure domain name that happened to belong to a masto instance years ago and find themselves bombarded by the federated timeline's collective traffic, a force tantamount to a distributed attack.
@garbados i started issuing domain blocks for a while as a stopgap, but it was a huge pain and started adding a bunch of load going through and deleting local content and media.
gave up after a while
