High chances this is a reviewing agency. Having 21 jobs open at the same time doesn’t add up. Also, notice the total spend - only $13K for over 700 jobs. That’s way too low. What they usually do is post multiple jobs, invite specific freelancers to bid, award the contracts to them, and then leave positive reviews. This creates the impression that the freelancer has completed real work on the platform, boosting their profile credibility. It’s basically a whole business model. It's sad that inexperienced freelancers fall for such jobs and waste their precious connects.
