I joined bux.to for long time ago, unfortunately when I requested my first payment they stopped paying people, it is been now more than 2 years since my payment request but still nothing, beware of the fake blogs and twitter account that bux.to is using, it is all been used by bux.to and updated by them. Everything about bux.to is fake, even the advertisement you are clicking on there site is owned by them, no one advertise anything on there site, those ads are affiliate link marketed by bux.to, if you click on them and it happens that you buy the product in the ad bux. to will get a commission on that.
They changed there forum, to a restrictively controlled forum, if you post anything complaining about the payment they will not approve it.
