I found an agency watermarked clip on a YouTube video a month ago and it was taken down very soon after I submitted a takedown notice. The thiefs have since re-uploaded the video but replaced my stolen content with the stolen watermarked image from SimonKR. I thought YT penalizes users if they get multiple complaints about the same issue. I've already sent SimonKR a link to the video (I'm not putting it here as I don't want to increase the views).
