Add Ban for subdomains?

[CurtisS]

Our forum is being flooded by registrations from subdomains of the .FUN domain. I currently have a domain ban for *.fun but this does not appear to work with a subdomain such as "[email protected]". Is there a specific syntax to include subdomains in the ban entry?
A search through the 2.0.X forum did not come up with any suggestions.
Thanks.

"*@*.fun" should work

Thanks, Michael. I will give that one a try.

This method appears to work as needed. Thanks Oldiesmann!

Maybe hit by the tor flood? check some ip's. Take a look at the mail adr. here, a tor ip > https://www.stopforumspam.com/ipcheck/23.128.248.26

Resorted to htaccess (deny) all of tor. Lots of ip's but works, zero problems. Updating the ip list once or twice a month keeps it effective.

Not that they ever managed to register (question system stops every bot) but wanted the damn s**t to stop hitting the forum with 1000's of daily vists.
