Problems logging BoonEx spam

My current version is Boonex Dolphin: Dolphin 7.0.6

And we have a problem, users are registering with strangers and to post spam, we have enabled the captcha, but we still have the same problem.

Hello

Take a look at our Access Management System module. It allows you to track spammers and block them by ID, IP, IP range or even the whole country. If you have some questions feel free to contact us.
