I have been recently attacked by bots, the bots registering with name+number to conflict with real users for instance zadicon79@prapor.men, bursodoct77@zalupa.clubalso, cordemas84@xeros.gdn etc. now i have google captcha and they somehow passing it, and also cloudflare cdn. i found on the internet a tricky way to prevent bots from registering to website http://devgrow.com/simple-php-honey-pot/ i think this method should be used in the next version of dolphin and in una as well as an additional security layer.
