It’s a scam for both, freelancers and project/job posters. For freelancers, they send you fake projects on which you can bid that lead towards nothing and then they send you fake projects that require you to pay membership, projects that would lead towards nothing as they’re fake. I can tell as I’ve worked for a very long time as a freelancer, completed 100s of projects on ScriptLance, RAC (vWorker), etc. Same is on the side of project posters, they ask you to pay membership to reach more freelancers and they initially hide everyone from you, so you can’t really reach anyone. It’s shadowbanning and scam 101.
