No it isn't. DMCA *is* the polite method of contacting the other people. All they need to do is respond "no it doesn't infringe" and the material is restored again, per the law. (It is then the responsibility of the owner to file a lawsuit.)
I would disagree, given that -- while not a legal requirement to do so -- many sites have a policy of suspending or banning users who receive more than a certain number of DMCA complaints. Thus, it has become an impolite method of contact de-facto.
