Blocking Destructive Users from Websites?

Posted by Cliff on from the eliminating-those-who-spoil-it-for-others dept.

billmarrs asks: "I occasionally need to block a user from using my website because they are abusing the system in some way, but the tools I have to work with for blocking them are easily circumvented. Once I identify them, I can block their IP; but they can just hang-up their modem and dial-in again to get a new IP. I can also stick cookies in their browser to identify them, but they can delete the cookies (or turn them off altogether). Are there other ways to block unwanted users from one's website?"

  1. PIII Track by BryanHughes · · Score: 0, Flamebait

    If they have an older Piii (or some of the late Pii's) you could track them by the ID on the processor. It would be interesting to see, but totally immoral. I'm wondering when microsoft is going to add client ID's into IE (such as a permanent id that's added on registration), or have they already? I believe they have a similar tracking feature in Office. Office documents are "tagged" and if you were crazy enough to register with MS, they have your id. Otherwise, if you were crazy to put in your real name at registration, they know who you are. Anyone want to confirm this?
