Thank you very much. This is the best advice I got.
I just have one fear remaining i.e. copyrighted pictures and videos. I know, I should not take pictures from online Magazines.
But still I wanted to know what is the exact definition of copyrighted content? I mean, on which grounds YouTube bans?
If we take a clip from a movie (e.g. a kissing scene) or a TV show (e.g. FTV Bikini Fashion Show) then would YouTube in future (probably after 1 year) ban us on copyright grounds?
May be after 1 year, we would have uploaded more than 6000 videos as OP did. He was working with his girlfriend while we are a team of 3 and we might grow our team if we see, dollars coming in.
And all of us fail in the end if Youtube bans on copyright grounds!
How do we avoid this?
