I still don't understand why everyone gets so bent about the Madis QC reports. I started reporting to Findu probably back in 2008 and it used to do that to me all the time. I got a little bent about it then I realized they aggregated everybody's reports and QC'd it against a baseline. As I saw on this thread earlier, its 'garbage in/garbage out'.
I learned to ignore it and enjoy the hobby. I check my QC about twice a year now. Since then I've never had a problem.
