I hope the API will stay online; we use it to keep abusive accounts out of Hive SBI.
Good to know, I didn't think anyone used it but me. That portion doesn't require updates as it is fully automated so it isn't difficult to keep running. It is quite handy but I don't think anyone found a good use for it.
I use it as well, its the first line of defense against abusive delegations on giftgiver.
