Average (legitimate) registrations is 2-3 per day. Over the last two days 150 spammers (all verified as such on sfs website) got past q&a, ips spam service, cloudflare and sfs plugin.
All showing validating as we require user validation, but never had quite so many dodgy registrations in the whole 18 years our forum has been active !!!! Surprised that some combination of recaptcha, q&a, ips service, sfs, and cloud flare did not stop them!
