I logged in to my youtube today and i got this notice with a strike on my account: Now the thing is, i cannot disclose my niche or video here, but lets say it was a video of a commercial of wooden chairs, and the thumbnail i used was of a fully clothed hot chic sitting on a chair. and youtube removed it, so does that mean that youtube allows you to use custom thumbnail but you cant use any which are not from the actual video ??? then wats the point ? and theres no way to appeal this decision , all i can do is acknowledge another point here to note is, i have two of my videos ranked on page 1 for same keyword, 1 week back someone flagged my first video and now it is age restricted because it has a girl in bikini talking in a breathly voice to a man, now after a week my second video got flagged for the thumbnail issue, IS it possible that some one or a potential competitor is flagging my videos purposely ?? or is there something wrong with youtube, also share your thought , what can i do ? shall i also find and flag videos of competitors ? (though i dont wanna do that as its immoral and a time waste) or i should just concentrate on my videos ?? please share your thoughts. keep in my mind that with this thumbnail notice i got a strike on my account. also i dont do PPD or any third party network, the only method i do is youtube adsense, i dont promote any other thing.
