anybody knows about readbud?

I know that site. I am a member of Readbud but I stopped working on that site even if I have worked a lot there and about to reach the 50 dollar payout. This site is a confirmed scam site. My friend was able to reach the payout but Readbud refused to pay her for so many reasons which are I find alibis and not accceptable. Obviously, this site will not pay anyone based on the reasons given so if I were you I will not waste my time with Readbud.
