I participated in campaigns on the CX platform, but now there are many participants and it is difficult to sign up for a new campaign. But the platform is quite convenient, simple and if everything is done according to the rules, then they always pay for your work. I had no problems with this platform, although it is not ideal and has a problem associated with transparency of charges, but I believe that this is not the worst thing that could be. There are other good platforms, I use some of them, including CX.
