I am also looking for a better way to stop spammers. I already have reCaptcha, and have that other feature that checks a service for known IPs/Spammers.
They still go through.
Mostly have a letters and numbers usernames such as jdjdhd8738383, or they have regular user names like JohnWillians with a gmail email that includes a name and numbers such as
JohnWilliams23@gmail.com
Anyway to auto-ban based on a criteria? Like multiple consonants followed by numbers?
Or can we block everybody with email .ru ?
Thanks
