Topic: banning
We are getting a hell of a lot of spam registrations, despite the anti-spam plugins. Many of them are from email addresses such as someone@hotaka3310.itsuki54.forcemix.online the sub and sub-subdomains change but also the main domains. Banning the main domain (forcemix.online), does not work and the combination of subdomains and their IPs vary widely. I tried *.forcemix.online but it, perhaps understandably, returns an error:
The email address (e.g. user@example.com) or partial email address domain (e.g. example.com) you entered is invalid.
Does anyone know how I can block registrations from such spammers?
