when i see this type of thing i really think how decentralized hive is.

Yeah, those guys suck, they never give a reason for the downvote. Typically they are after plagiarism. Maybe the videos you posted raised a red flag? or it could be they just don't agree with our politics?
Just goes to show censorship is alive and well here on HIVE.
You could try posting on VYB (https://www.vybrainium.com) there is no downvote there or at least use the VYB tag also POB.

Hive is one of those things that I always seem to realize new things about. Maybe the price if HIVE is doing well because of people downvoting all over the place. Like crime kept in check by police officers enforcing it, sometimes selectively.

Pro Tip : Stop complaining or you will have everything zeroed out. This is the way Hive works.
