Hi Birmu! Thanks for taking the time to share this with us! If you don't mind though, I'd like to address a few points.
In your Worldwinner pros/cons, you list "Limited number of warm-ups games." What do you mean by this? If you're talking of the free game listed as 'Warm-up', then there's no limit to how many you can play. One can play those to their heart's delight, and I use it for practice quite a bit.
Also, you say that Worldwinner withholds 30% of your winnings if you're not a U.S. player, which is true, but I think that could use a bit of context so it's not misinterpreted (We're not Fox News here). Your winnings at Worldwinner are taxed by U.S. law. Since Worldwinner is a U.S. based company, even if you're not a U.S. citizen, you still have to be taxed on the money you've made there. This can be done either through non-resident tax forms along with the standard tax-forms, or by allowing worldwinner to withhold the taxed amount and sending it to the IRS.
Why is that a right? And moreover, if knowing the amount deducted for management fees is a right, how is this a violation of the alleged right? You can find this amount by taking the number of entrants in a given tournament, multiplying that number by the entry fee, then subtracting the prize payout to see how much Worldwinner deducts.Lastly, I have been unsuccessfull in finding the exact amount that is deducted from the tournament entry fees that go to Worldwinner.com as management fees. Unless they're doing something shady, members have the right to know how much of their money is actually going to the company.
