We are both been accused for the same problem. For me CP rating doesn't even matter. I just do it for fun.

I think they should take some action

Nor I have copied the solution from somewhere nor I have shared my solution with someone else by my own wish. I don't know how it matched. I have a self made template. Last contest I submitted only one solution. This time I solved 3. No. of solution was never a problem. I think someone shared my code in such a large scale then they deserve punishment. Orelse I don't see so much coincidence. I solved using an online complier. I couldn't submit it early because website was not verifying me as a human. My solution was submitted by another friend whom I myself shared my code and I am sure he won't share with anyone. Please don't delete my contest. I accept to lose points rather than getting tag of a cheater. The online complier was normal complier so I don't see any chance of getting my answer leak there. The only way of getting my answer leak is codeforces website. I may be wrong but thats what I feel.
