@evan@cosocial.caHi Evan,you are the developer of tags.pub, right?!It looks to me, that tags.pub works with HTTP Message Signatures according to RFC 9421 only. It this correct? No support for Signing HTTP Messages using draft-cavage-http-signatures-12?I'm trying to teach my #ActivityPub based server named #Mammuthus RFC 9421, but currently it isn't really working... sigh.So, if you see some weird follow requests on tags.pub from a #Mammuthus instance that looks like a test, it could be me...Using Draft Cavage 12 i get a 400 back.Switching to RFC 9421 (work in progress, testing), it results in a 401... and now also in a 400.Still investigating...Just wanted to let you know, i'm a testing developer, not a weird spammer or bot or... And i appreciate, when you confirm my observations... CC@swf@socialwebfoundation.org
