I saw my account in your video because I often join freecompliment's weekly art contest...
But regarding the issue, I understand what you mean. It's an advantage for users who have enough HP to delegate to those accounts, and it becomes a cycle that could create unbalance in the platform.

I still believe it's better to have real engagement in the platform, though.
I mostly just make content I like and sometimes I join contests for extra rewards and to meet more people on the platform.
