Yes, but ones who can't play worth crap should keep their music to themselves until they've practised it enough that it is actually worthy of performance.
This is what I don't understand. These kids are filming themselves doing these tricks. They can obviously WATCH THE VIDEO themselves after they've shot it. How in the hell do they NOT see when they blatantly expose the workings during a performance???
I have no problem with them posting videos of themselves performing what ever effect they please, just make sure it looks damned good before you put it up.
Have they never performed live? (might be a dumb question) They should realise what happens when you mess up, and the audience sees how you do something.
No, not just that the secret is exposed, but you look like a fool. Anyone who's ever messed up in performance should know what this feels like and how it can make you look in the audience's eyes, at least for that moment.
The difference is in live performance you can recover and move on to another effect, when it's on youtube and it's just your single effect performance, that is all you leave them with, and YOU MAKE YOURSELF LOOK LIKE A FOOL.
Plain and simple. If you aren't going to have enough respect for the secret and the fact that when you mess up you expose it, then have some respect for yourself and realize when you mess up, you expose yourself.
