For anyone unaware of the the spam issue mentioned in the link, it has been ongoing for a week. Some person or group is generating accounts on open Mastodon instances and spamming crap all over. My instance's admin bot caught ~~two~~ three new spam accounts while I was typing this post. I know admins at other instances have put similar protections in place.
If you haven't seen the spam, thank your mods and admins!
