1. Who you are asking to? If Geel and Jesse, then of course, they made this site to make profit anyway, especially from banking thingy. If it's Mod, S-Mod or any other staff, maybe, I don't know
2. Pretty much they get profit from in-game currencies, some real-money from donators. They can trade those to real money anyway
3. Geel is gud, Geel is life. Gaben is overrated
