The main problem is that they're all about quantity and as a result not very transparent on how services are evaluated. If you want to cover ALL services I can imagine why they took this approach. I do more extensive reviews and that only results in two reviews per week at best - it takes a lot of time. Still I prefer that over potentially listing a site as safe and not being able to explain when things do go wrong. In the end you have to find some balance between quantity/quality I guess (knowing new scams pop up every day).
