Eh, why not. :)

Difference between lvl2 and lvl3 is relatively small in user base, and the level 3s probably thought the level 2 one will be too densely populated in time. (It should be, usually the auto-entry bots arrive in the last 10 minutes, just look at the low difference in the level 0 and level 1 giveaway. It will increase.)

Or just a strange phenomena in the system. =D
