Better not take the risk, no genuine company will pick writers from other paid platform, especially one that is more well known than yours, believe me no one is better than an Indian in recognizing scams. These people know that most of people posting here are students who don't have stable income sources and will not leave a chance to get extra cash and probably can't afford a lawyer if they get scammed, which would cost more than the money they got scammed to give these sites. They will probably ask for your bank details sounding all professional. If they were to use your work they would have done it without asking you.
