When I first started writing for Crowdsource, all of my work was accepted and I had a high rating. After a short time, I started receiving many rejections criticizing points that had previously been accepted. I would definitely agree with others that the editing is very inconsistent and that style rules accepted by one editor are criticized or even lead to rejections from another. Also, it does seem that resource guidelines change, overnight. Last week they accepted Wikipedia as a secondary source, this week I received many rejections based on it no longer being an acceptable source. You can make some money here, but I find it really interesting that my experience seems to follow a similar pattern to others - who are at first well rated and then receive many rejections. It does make me wonder if there is something going on about preventing writers from advancing there.
