No, because it's retarded.

I'm not sure about who has tried that before, but I know about a lot of people that got really good at codeforces and didn't try this. (sorry for bad english =) )

They agree (and me too) that the best way to improve is to try your best solving the problem alone. Because if you get used to reading the solution you will become lazy at thinking and probably have bad results reflected in your ranking.

By doing that you wouldn't train your problem solving skill. But I think it maybe still be useful if you want to get familiar with different approaches used in editorials. As a conclusion I think if you already have decent problem solving skill and want to get grip of approaches and topics in competitive programming it is probably good strategy.
