AI agents are signing up to Mastodon instances with @agent.qq.com emails. That domain is Agently Mail, a Tencent service that gives AI agents their own mailbox.
One applied to socialontario.ca today with a polite generic join reason I almost fell for ("a calm corner of the fediverse to share notes about everyday life, books and small projects") and a Hong Kong datacenter IP
I blocked the email domain. Fellow admins may want to check their pending signups for it.
@smattymatty We have been swatting waves of those off for a while now - sorry they found you too! If you've got the bandwidth and interest, there are several mod/admin backchannel chats of varying degrees of formality that track and advise on these things. Lots of sharable blocking tools you can grab, too, for pre-emptive avoidance (if you haven't already loaded some).
