The following thread explains clearly how to remove exposure videos from Youtube. It is illegal to do this, I will not deny - and that is why I have made a puppet account here so as not to cause haters.
I have always opposed exposure of magic, and there is much of it on Youtube. I have removed ALOT of it myself, including hundreds of old "Magic's Biggest Secrets Finally Revealed" videos, and many explanations of how "Flying" and "Portal" are done. These videos ruin the experience - because they are right there in the "Related Videos" bar.
If you do not wish to remove videos from Youtube, I do not blame you. But I hope fellow magicians will agree with me that -although this is somewhat an underhanded method- it is necessary to counteract exposure and ruining the secrets of magic.
Step One: Find the video you wish to remove
This can be as simple as searching for "Criss Angel walks on water revealed", or "magic secrets revealed" and finding any videos that expose magic.
Step Two: Flagging
To remove the video, it must be flagged for copyright infringement. In other words, you must pretend to own its copyright. To do this click on the little flag below the video screen, it has the word "Flag" written next to it! Clicking this gives you several options, and you should select "Infringes my Rights" and then select "Infringes my Copyright".
Step Three: Getting the copyright information

(this can be found by searching in google for "Copyright registration number")
This is where you can find out who owns the copyright to Youtube videos. I shall give you an example, if you are trying to remove Masked Magician videos then you search in the search bar for "Magic's Biggest Secrets Finally Revealed", with all the correct spelling and punctuation. It will bring you a list of all the series, and you can click whichever you feel is most appropriate. In this case the later series are made by "Bruce Nash Entertainment", and it also lists useful information like the copyright registration number.
Step Four: Removing the video
Once you know who owns the video (if no one owns it and its a home-made video, just invent a company name), go back to the first page you had and click on the "Flag" button as before and select "Infringe my copyright". It should take you to a page where you can fill out information; insert your own name, details and so on, all your own information, apart from the first two which are the copyright holders buisness company, and your job position, which I always call "Copyright manager".
Step Five: Finishing
Insert the URL and the name of the video you wish to remove, and select it so that its "My Video (not from Youtube)".
Once this is done an email will be sent to your registered Youtube account address and within a few days (3 or 4 at most) the video will be taken down.
If they ask for further information, they only ask for information that can easily be obtained from the US copyright website that I linked to before.
This may be seen as underhanded by some, but it is actually helping the copyright owners, as well as magicians. I hope people find this thread useful, and will not hate me for it. I am a big opponent of exposure.
