An IP address blacklist like [[m:Spam blacklist]] would make it much easier to
deal with open proxies (currently managed manually by the [[m:WM:OP|MetaProject
on open proxies]]) and crosswiki vandalism, particularly if it recognized CIDR
ranges. The blacklist maintained by the MetaProject would be a good start. If
some wikis prefer not to block such proxies automatically for some reason, they
could toggle it off much as can be done with the spam blacklist.

It would solve a problem that is currently overwhelming us, involving a static
IP address spamming every Foundation wiki with legitimate and widely-used links
in petty revenge for an administrator's refusal to spam blacklist a legitimate site.

The only current solution would be for a steward to manually create an account
on every Foundation wiki, assign admin access to every account, and block that
one IP address on every wiki. This would need to be done again if they used a
different proxy. This isn't very workable.

The spammer is causing significant disruption on many wikis and can presumably
continue doing so forever; since this is the only workable solution I can think
of, I set the priority to 'high'.
