I got this request to install this IP blocking extension a long time ago (https://ms.wikipedia.org/wiki/Wikipedia:Kedai_Kopi_(lain-lain)#Blocking_IP_ranges_of_Arab_string_vandal) in Malay Wikipedia.
They suggested us for blocking only Arab in there but if possible, we want full IP editing block. because now there are so many vandals come from IP users in Malay Wikipedia.
Is it possible to block only certain Ips? Sometimes there is an IP that is ok to edit. Or do you have a system that blocks only the creation of new articles for IP users and users who have just opened an account?
