Youtube cheat for higher cpm?

Hey guys,

I just had an idea and wanted to know if somebody had done something simmilar and if this might work. When you already have a good subscriber count and you get on the browse page and suggested view page quite often, can you change the tags of your video to something that has a really high cpm like car insurance or similar words, to trick youtubes ads and get a nice cpm boost? I know this would be quite blackhat but is this possible?

nah.. you just mess your video rankings.

This is a good instruction of what is better not to do.
