I have every anti spam feature built into xenforo turned on (dnsbl, stopforumspam, akismet, etc). I'm using google recaptcha nocaptcha
One characteristic I've noticed, they're 100% non english. Looks chinese to me (not that I'm an expert)
Is there a good way to force people to only use ascii characters for their first 10 posts, and if they fail, they go to moderation?
Should I use a different captcha?
