Bizarre scoring for 'Mika's Cuck'

[666]

I've never had a tease score so oddly, it started at 4.2 and dropped dramatically to 3.6, climbed slowly to 4.1 (suggesting that there have been quite a few votes and thus it was stabilising) but it dropped overnight to 3.4. Did someone bombard it with 1's somehow? I don't get it...
