Discrimination in iPhone app

I downloaded a free game on iPhone called tap tap revenge 3 and b4 I could start playing, I've to set up my game profile. I was required to key in a user name and select my avatar. And that's exactly what I did.

I typed "Jez" as name and picked a sassy looking girl to represent my rocker chick gaming attitude.

But before I could proceed, a note popped up to my dismay saying "too short".
For a moment I was really offended, and then worried how this new app knew so much about me!

I later found out that it meant my keyed-in name was too short.
Well there u go, tap tap revenge 3 has no height preference for its players.

So play on!! all ye iPhone addicts!
