Hello, There is user which is abusing my board by regsitering multiple accounts from different IPs and by using email addresses. He has registered over 200 accounts,i am banning him once he make bad posts,but he still has tens of accounts regsitered. Thats not bot,thats human beeing. The question is whether if there is a tool to identify users using the same computer to regsiter multiple accounts ? Probably by cookie or pc name or similar.
PC name cannot be known as its blocked by ffirewalls and Anti Viruses unless the user allows that. Cookies can be easily cleared with one click. No similar way...
You might need some type of script.. maybe what you can setup is that all new posts by new ppl have to be moderated. I'm not sure, but it's something to consider. I would also report them to their isp.
if he is doing this 200 times i think he is using a script, you maybe could install a captcha script so he has to enter a combination of letters/numbers before he could submit the registerform.
