Definitely, it is always very important for you to see payment proof from websites or even people you know before you join any platform. Checking reviews is also very important because it will help you to know if a particular platform is paying or not.Some website online are scam that is why you need to see a proof of payment before you can join a site,I work for so many firms online but at the end of the day I was deny a pay,so for this aspect I think now I have to be extremely careful before I can decide to join any site
