Hello i have web side with videochat http://lubalove.sk//chat.php we have problems with specific users which are not follow terms of use. We have block on IP, and cookie. But they change IP and cookie and in 5 min are back. Is there any way, how to identify users according number of operating system or something else? How can I protect and keep them out from this kind of users?

Using the OS is not a good idea, there are only a limited number of OSs out there!

Why not get them to register and block by email address?

Do they have a completely random different IP every time, or is the IP within a certain range? If they're using an ISP with dynamic IPs, you could just block that IP range.

Other solutions may be: enforce them to enter a captcha before registering, and let them click on a confirmation link before activating an account, which you email to them. Wait a few minutes before sending the email.

We have now system to block these people according IP and cookies. Many of them have dynamic IP addresses so they just switch off and on internet connection and get new IP. To close dynamic IP range thats means to block sometimes 65025 IP adresses. Here are some IP ranges
91.32.0.0-91.63.255.255
91.127.0.0 - 91.127.127.255
91.127.0.0 - 91.127.127.255
78.99.0.0 - 78.99.255.255
78.99.0.0 - 78.99.255.255
78.102.0.0 - 78.102.127.255
84.47.96.0 - 84.47.127.255
We need to build some system how to identify users not according IP and cookie but something else. Captcha is not right way because its real people which can type code from captcha. I dont believe that there is no way to identify user. I thought maybe MAC address with trace route protocol.

issue PIN numbers to legitimate users.
