207.44.154.35? Hell, I blocked him on the Welsh Wikipedia last Wednesday for vandalising [[cy:Hafan]], the Main Page to promote some "NESARA" rubbish (it wasn't even in Welsh, which might be a little more forgivable!). He was back today doing a minor bit of vandalism to one of the date entries, and got blocked again. Is there any way to permanently block an IP address?
207.44.154.35 is the popular anonymous proxy http://www.anonymization.net, and as such is used by lots of different vandals. Anonymous proxies are regularly used for vandalism, and once we block one, the vandal just moves to another one. On meta recently we've had a bot operating to vandalise tens of articles, via an anonymous proxy.
Would there be any objections to systematically blocking all anonymous proxies on a site-wide basis?
