Five more attempted signups from that ‘Automated protocol deliverability probe’ nonsense. I guess replying to the email didn’t do the trick. Shocking.
Alrighty then, banning signups from gmail mail accounts it is.

@fname It's gone a bit quieter for me. I had none today, 3 yesterday, and none the day before.
I've got a few hundred IPs in my blocklist now for it tho :(

@chewie @fname They are probably using TV sets as proxies, so blocking the IPs won't do much.
Their goal is to sell mail bombing services.
Here's a German language blog about it: https://troet.fediverse.at/@ilanti/117292822473594624

@gunchleoc @fname Quite possibly, but I'm still doing it!
Thanks for the link!

@gunchleoc @fname maybe, but other crap might originate from them in future too, so I'm fine with that. It seems to have calmed down for me, so either it's working, or they've moved on.
