so on #Bluesky, rather than going with the well-documented and defined webfinger protocol, behind the .well-known directory, decided to make their own shit for verifying domains via HTTP (to change your handle to the website, proving your ownership of it)
thus, somebody took the S3 bucket name "xrpc" and now is s3.amazonaws.com on the platform
going great
