No flaming... just the mention of the practice, send chills down the backs of many of us. It is a good question, and one that all should be familiar with. There are fly-by-night types, who like to create their own grading services and can be very misleading.
If you want to know, you got to ask. Keep asking, it helps everyone as it is sometimes a topic someone else has not even considered yet.
