I have investigated this website as part of my job and company funds. This business needs shut down! The "winners" are consistently the SAME accounts and unless you spend hundreds or even thousands of dollars, there's no way to get more votes than these accounts. A few of these account owners seem to be related to or connected to the owners of the company, Playground.
Furthermore, when you start getting enough votes to get close to having more than the regular winning accounts, the website either won't let you login or they start cheating you out of votes, even the ones that you purchase!
Don't waste your time or money! I am unable to login now. I get a response saying "too many login requests, try again in a few minutes". It's been 3 days. The contest I'm in ends in 3 days. I suspect I'll get access after it ends so there's no way for me to win this current contest.
