I have serious problem with spam registrations. After few hours my hosting provider is blocking mail function bcos web is spamming!
I have WP
v. 4.7.5., ClassiPress v. 3.5.8
I also have secured website with captcha, wordfence installed and disabled login page.
After turning on mail function the robots starts registering to website and I don't know how to stop them.
Please give me some advice!
