It is a scam. All you get is exactly the same message from what only can be bots. Most accounts seem to be inactive. I sent messages to tons of people just to prove they are not active. I wanted to try out for a week, payed what they asked for $4.75, but they charged additional $13.24 for upgrade for something I did not understand or authorize. After charging almost $20, my membership expired after a week, though the receipt said the upgraded membership is for a month. They tried to charge my card again after a week, but I am not a fool to use a credit car at a site like this. I used a $20 Visa gift card. So, they were not able to charge again without my permission since the card didn’t have sufficient fund. Guys, use either Visa or MasterCard gift cards available at every supermarket, walmart, CVS, wallgreen etc. You can buy them for cash use them for online purchase with a made-up name and, if asked, a made-up address. Don’t use real persons name or address. This way, you don’t have to worry about they charging more than what you have on the card.
