Basically played so much on different sites that our taxauthority never tracked and also played lots of promotions, private or affiliate games which also often don't get tracked at tracking sites
Leaderboard wins also never get tracked,most freerolls don't get tracked, believe any RB also can't be tracked. Special exclusive buy in games often also won't get tracked, so a lot of winnings if you game select very well are hard to find, I am also using Ewallets to get my cash, so obvious won't do it through my bank
You gotta take into account that I am playing profitable poker for over 6 years now and have two kids and two places, so I really needed it to pay all my bills
