It doesn't look like the ban evader sock anonymously according to the BlockList. However, as suggested, you can poke one of the VSTF on their talk page in the VSTF Wiki to see if they can issue ranged block, but since you've said that they used a vpn, then there's really no quick solution, so range block does little to no effect.

However, I don't see the wiki is under a massive attack. A total of 6 blocks (not counting autoblocks) since November has been issued in the wiki. On December, they've never even come back for two weeks thereafter since their last block on the 11th of December and 28th of November. So local block without range block should suffice.

Even if you set up AbuseFilter to prevent the word "den" used in the wiki, they can still bypass the filter, by not using the word thereafter. But it's a good way to slow them down, though. However, if not filtered correctly, it can cause many false positives.
