Yesterday I had an okay round 427. I solved 4 problems and... got kicked out. Presumably I leaked my solution on ideone and someone copied and paste my solution.

I know I am partly responsible for this cheating event because I "published" the solution during the contest. I will take this lesson seriously. However, what makes me unnerving is that delete4 still preserves his competition results of round 427 and had a decent rise in rating.

I am deeply frustrated and confused by codeforces' decision. Why did delete4 get a different treatment from me if we are both caught "cheating"? Is it merely a small mistake? Or someone is convinced that I am the only one who is responsible? Or there are other terrible things going on? I hope the people who is in charge can give an honest response.
