Suddenly "You're Banned" on PTC Site, Scam Site

Yesterday, I tried to login to my account on http://10Bux.net/ but when I successfully logged in, it displays "You're Banned". I don't know why. I don't have multiple accounts. I only have one account. They didn't just even inform me why. My efforts of clicking ads for weeks was lost in just one day. It's really discouraging. :( Therefore, I conclude http://10Bux.net/ is a scam PTC site, be careful.
