Oh dear, man, don't get me started! :P The Hitler parody content is, in fact, property of Constantin Films, so they claim videos of Hitler parodies. They have no negative effect for us, just a notice saying that the video features audiovisual content administered by Constantin Film, no blockings or anything (provided that you don't use excessive amounts of footage, otherwise they think you're just uploading the whole film). It was worse in the past. In 2012 (and for about 3 days in early 2012) Constantin would block parodies. Also, in the past, fake copyright claimants have blocked parodies (but we've managed to dispute them no problem and they don't crop up anymore. I hope this clears up what you're asking about :)
