Frankly, I'm not so sure that disabling achievements would have all that much of a negative impact on the wiki at this point – I imagine that many of the positive contributors on a moderate-to-large wiki like this one would be making the kinds of edits they've been making regardless of achievements, and I would guess that even the people at the top of the leaderboard would probably not be particularly vexed by the loss of some imaginary internet points.

If I'm correct in this assessment, I'd like to think that disabling achievements would have a net positive effect on the community, not the least of which would be drying up these spam blogs...though it'd probably be best to wait 'till more of the people who would be most "affected" by this change are around to start a forum post about it.
