Hello, I am receiving many fake registrations on my whmcs. I have tried enabling google captcha, email verification, and the problems continues. I woke up with nearly 100 new accounts created this morning. I am now banning email addresses which seems to be working, however when they use a new email the problem continues. I wouldnt even mind disabling registration all together, as I personally register 99% of my customers through the admin panel. Can anyone offer any suggestions on how to get this issue to stop, and if not, is there a way to disable registration? Thank you for reading!
