oooh. these are always fun to try to figure out!
the level jumps are at least plausible this time around, and it very well could just be a top 5 player's alt account. of course, to do this they would need a great win rate against top players, and i'm sure someone here would recognize playing them.
naturally though, i am a bit skeptical, due to the existence of a player named Feed Me More who is shockingly below level 0. what is more incriminating then that though, is that when i looked back i found that account at least as high as level 16 back on
November 1. (and that 16 level drop is not just due to variance increase over time.) this 'Feed Me More' account hasn't picked up as many games played lately, but im guessing they just switched to another lvl 15 or so account to beat up on. this other account would be hard to find, but we can easily use Feed Me More to track FEED ME MORE's rise:
11-08-2012 FEED ME MORE +7 Levels, +24 games
Feed Me More -1 Level, +20 games
11-07-2012 FEED ME MORE +4 Levels, +6 games
Feed Me More -1 Level, +5 games
11-05-2012 FEED ME MORE +5 Levels, +9 games
Feed Me More -2 Levels, +11 games
not bulletproof, but i think occam's razor would agree that it is just another cheater.
