New users must post a comment before grading or rating
We’ve added yet another measure to help make sure that new users understand the purpose of IM Report Card, and to help make sure that they are capable of providing value to our community.
Effective immediately, new users must post a comment that is approved by our moderators before they are able to earn credits from grading products, or submit ratings of reviews or other users’ comments.
There is a lot going on “behind the scenes” to help ensure our grading and rating systems are as accurate as possible, but this is just one more added to the list.
For some strange reason a small number of users think that we are some kind of “paid to click” site where they can earn easy money just for grading and rating things (probably things they’ve never even used) and so this should help deter them even further.

This seems like a good idea.
Great idea but is the comment linked to the same site user is trying to grade? If not, how can anyone grade a product they have never used?
Good idea, but something must to do well.
