Hmmm, every server I'm getting spam from has a new user in their public directory named yqqwe, and each one of these users is following mastodon_admin_yggwe on a single-user instance mastodon.tinynews.org. One can look at the 924 followers of this admin and they all are named yqqwe and they are all on servers I've been getting #spam from. #fediverse#moderation#administration
I've found a few of these servers do NOT have the yqqwe account on them, these tend to be more active servers with admins moderating/removing spammers. Good!
