Fedi, in recent months, I've noticed more and more that servers are no longer communicating their blocks. I think this is a very bad practice, among other things because the transparency to the user is lost, because users push the problems on the technology/their own instance and not on a server block. It is also not possible to determine if administrators are doing their job correctly and maintaining the blocklist.
Could one please start sharing blocklists according the specs again?
