Over 100,000 new users here since I stepped in 2 months ago, nearing 400,000 total users soon (if not already, haven't looked in a bit); about 20-25,000 active users in any given 24 hour period (roughly 6%). This does reek of something amiss.
But you know... as long as those high-dollar self-upvotes keep working for those guys I guess the code is doing it's job.
