Hoi,

A user of the nl:wikipedia who had the misfortune to be blocked on a proxy server, mentioned that many providers send a HTTP_X_FORWARDED_FOR header along. This she said could easily be retrieved using PHP with the variable $_SERVER["HTTP_X_FORWARDED_FOR"]. Now when this is true, it makes excellent sense to use this IP-adress for the registration of contributions but also for the use of blocking specific IP numbers.

I have no idea if our software uses this or not. I thought this a great idea so I move this remark to you in the hope that we can enhance our software and make our anti vandal solutions more accurate.

Thanks, GerardM
