My website has had a lot of spam lately, mostly lots of people signing up for an account. I know I’m not that popular LOL.
Anyway, I added a spam blocker called CleanTalk for $8/year. It validates registration, commenting, and contact forms without adding CAPTCHA, questions, puzzles, etc. It also checks my store checkout form.
It seems to be working, all those registrations are gone. So if you are having trouble registering or filling out any type of form, send an email to me at firstname.lastname@example.org and I see what’s going on.
