Your version of "constructive criticism" would probably be turned in by the community as spam or harassment. Its going to be fully open to the community.
I am the marketing manager for DIY Tube Video Community.
The people will decide for themselves what they approve of.
So you don't allow criticism of yourself - even constructive criticism? This is why you have a forum dedicated to you. This is why this forum http://troybusters.com/troybusters/forums/ exists. All the members of that forum were labeled 'Trolls' by you, just for giving advice. Anything you didn't like in the comments section of your YouTube channel, you deleted. And it appears from your answers here you would do so on this so called platform you are promoting.
Then there are the scams ............
This is why we are here.
