While valid, I would point out that it should be expected at a low user count. Girls make more money right now, later on guys might when a female population shows.
Some people might walk in here and drop 10k to become an instant sensation.
I get the frustration, I really do. I think over time with more users coming it will even itself out on it's own.
This is another one of those excuses though. My proposal is very simple, minimally invasive and solves this issue.
