@Yuvalne @alternative @dansup Same happened to me!
When I posted about the spam publicly, the bots started to register in my instance but suspended them asap.
Some of them have the same IP address while others don't so it seems they are behind a VPN. IP blocking might block legitimate users who use a VPN to prevent ISP geoblock. Not an option for me. I am not 100% sure what to do beyond manual check.
@trankten @alternative @dansup
I checked some of the IP ranges and found one where most of our bots lie but also one of our users. so I just restricted sign ups from that range for 1 month.
