Hey #MastoAdmin / #FediAdmin folks, there's a spam wave happening.

They are using QR codes with random color schemes so you can't use blurhash filters. And there is no text other than username direct mentions

Spam usernames are random strings, on poorly moderated servers as usual

Anyone have recommendations for mitigation?

If you don't have an admin team that can handle properly auditing account registrations and dealing with reports quickly, I strongly recommend disabling open registrations on your servers for now

@neatchee heh, if you don't disable open registration (or at least email + captcha) you get several new accounts a day that never post but somehow output traffic (spam DMs?).

Also, curiously, there's been a bunch of Matrix spam lately, too. Invites to DM and invites to external servers.

@neatchee we use this project
github.com/halcy/mastodon_mod_
It runs small ML models to calculate similarity of text/images

Just now, I tried to throw some spammer QRs into it, and looks like it works. There will be false positives, so you should monitor generated reports

@mo @neatchee

I wonder if this tool could be modified to check for QR codes in images, decode them and based on the contents of the QR codes ban them
