IWriter is an example of a mistake I often made: joining and working for a company without researching other people's experiences. I later found many negative reports.
From my own experiences: while the pay is so low it took weeks to reach the payout minimum (and that only occurred because one client liked my work so much that she sent direct orders), it's the bad business practices that I really objected to. As I'd never had any written material rejected before, I didn't know what to make of it when one article after another was rejected. It wasn't til I started reading about other people's experiences that I learned rejecting work and then using it anyway was a common scam clients engage in on iWriter.
The website- at the time, anyway- stated clients can reject work that is poor quality, filled with errors, etc., which is logical. However, that was not the case with articles they rejected. Although I followed instructions "to the T," the feedback I received was "Not what I wanted" and "Not what I'm looking for." Upon contacting Support, I was told clients can reject articles for any reason.
So from my experiences, I believe other reviewers were correct when they said iWriter allows clients to steal writers' work. I do hope the person who said he planned to sue the company is following through with it. I tolerated these jerks at iWriter for a few weeks a couple of years ago, and it is by far the lousiest and shadiest online company I've ever dealt with in my 13 years of freelance writing. But that's what can happen when a person is desperate for work and jumps into a company without checking it out first.
