After being paid a somewhat large amount after working a lot for a week, I realized that I was not being shown any more jobs and my reviewer status had been downgraded to only editor (when I had not worked in at least a week). After asking them why I did not see any jobs, I was told the jobs were being shown whenever they were available. I then emailed again to say that I had been talking to other reviewers who told me the same thing happened to them: after a big pay, no more jobs available but other reviewers could see that some jobs were indeed available, just not shown to this particular reviewer. Their response to me pointing thid out to them was to close my account for "low quality" (when I hadn't done any new jobs in a while and my grade was still good) and prevent me from contacting them again. They are horrible.
