Thumbs Down

I know what I post isn't for everyone, I get that but if you are going to give a thumbs down at least state why. Hell I either don't post or delete videos because I feel like they are boring or I think to myself Ive done that before but whatever I post gets thousands of views! So are the thumbs down just hating ass trolls or are the genuine opinions of individuals who really have some constructive criticism to offer?
