Forum:Restrictions on new IPs?

Well, it looks like we had yet another sock puppet (http://masseffect.wikia.com/wiki/Special:Contributions/190.93.190.1).

Even though these incidents are not that common, I wonder if there are measures we can take to further minimize these sorts of harassment and vandalism. The behavior of these types of incidents seems consistent with someone on the wiki using TOR (http://en.wikipedia.org/wiki/Tor_%28anonymity_network%29), mirroring even patterns of one-off IP vandalism that wikipedia suffers from.

Now, I'm not speculating about trying to find a way to block TOR exit nodes (which wikipedia has struggled with as a policy: http://en.wikipedia.org/wiki/Wikipedia_talk:Blocking_policy/Tor_nodes, http://en.wikipedia.org/wiki/Wikipedia_talk:IP_block_exemption/Archive_1#Evidence_that_the_world_won.27t_end.2C_and_a_counter_argument), but maybe there are ways we can limit the permissions of fresh IPs? I know wikipedia has permissions categories like "autoconfirmed users," and I wonder if there are ways to just prevent anonymous IPs from editing user talk pages, etc.

Obviously I don't have a firm idea in mind; this is why this is not a policy proposal: I just want to brainstorm and see if others have any ideas. I'm also not quite sure what tools admins have at their disposal. I just know that even a 1-year block for vandalizing IPs (as was done to 190.93.190.1) is kind of pointless because under TOR one person's displayed IP can switch from edit to edit.
