I imagine Andy is pretty savvy at SEO on youtube.
It's typical of youtube's algorithm to throw a bunch of videos
into your suggestions based off of one video which was typically
uncanny to your normal viewing.
One time I watched something like 'scary scene in IT'
and then was bombarded with horror film top 10s for months after.
Because Andy's videos having enticing captions and thumbnails
people outside of his targeted demographic will normally click once
and never click again - yet get multiple suggestions then after.
Andy's optimism and business ethics are pretty sleazy, something you could
refer to as astro-turfing.
People's aggression to his videos on youtube however, just perpetuate his online profile.
For example when kids make comparisons in the comment sections of his videos by name dropping Luan and Nyjah,
this further ranks his content among suggestions based off those two aforementioned skaters.
It's like a vicious circle, that he's tediously won over
