^ B10n1c is capable of creating a filter like that; he told me himself. He's tied up in some other matters at the moment tho, so maybe later? Although a community vote would also fall under the category of "maybe later," with a huge emphasis on maybe, and by maybe, I mean probably not. -___ -;
Also, doing an IP check on the 4th ban vote's results would definitely be a legitimate option. Since there was no restriction to IP addresses, naturally people would just use the same IP address instead of going through the trouble of making a new individual IP address for each account. All we really have to do is check for the number of unique IP addresses that have voted for each side.
Counting it up by hand is a monstrous task; I tried, by using the criteria of "users who signed up before August 2009 and currently have 100+ posts or more," and gave up before I finished the second line of users... we're gonna have to call in a favor on this one...
