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.
Yeah as I said a few times in the video I wasn't trying to single out this one particular user, there's many doing it in way worse ways possibly. Your username popped out as one of the few real users commenting on his posts as there was a lot of bot activity inflating the numbers from the outside.
