Hello,

Lately on fr.wiki we have a disruptive person who is vandalizing daily using transparent proxies. We have blocked the IP range he is on but he can still edit using those transparent proxies. With the check-user tolls we can see his IP address in the XFF headers. Would it be possible to implement a way to block an IP address from editing through transparent proxies using the XFF headers?

BTW there is an opened bug for that: https://bugzilla.wikimedia.org/show_bug.cgi?id=23343

Thanks in advance,

N.
