Why

Recently some people are broadcasting the solutions of problems during contest time. In last div2, a guy literally came live on youtube during the contest. It's like "Study with me"'s newer version "Cheat with me". Can codeforces prevent these kind of things from happening?

(This is not my real handle, so if cheaters downvote I don't give an f). I mean why should I give an f to some lifeless fellas, who the hell told you to do cp, go do something else.

Codechef is not organizing any rated contests for more than a month, recently they organized two contests but both of them are unrated. Do anyone know what happened? Another thing, codeforces contest's div2 A,B,C are now based on arrays and strings most of the time. Can we get something different?
