Okay.. the "No action is required on your part.." part means "we've just deleted part of your video" but we've worded it in such a way that you won't freak out and go check your account. I knew something was up when it took almost an hour to upload a 2 minute video. Wow! They must have some kind of carnivore-type of software. My video was up less than an hour and only had 1 hit before it got flagged. Anyway.. be warned, big brother is here.
