I was just reading some recent blogs, and out of interest I saw ratings of OptimusPrime090, the graph took a wild spike in the last contest (#727), and when I explored more into his recent contests, I found that he had got a rank of 1k by solving 0 problems!!! (whereas I got 2417 in the same).
Is this a bug or something else I'm confusing with, as it looks very strange to me!
Look at the submissions. They are skipped. Probably for plagiarism.
The solutions have been skipped. The ratings will change soon.
Hmmm, then it's fine.
It's impressive to get rank 1006, even more impressive by solving 0 problems.
