So to sum this up, everything fits in here:
OP takes videos from live streams or create from scratch some fake hack for gaming, and few other niches.
This content is 100% unique, and not under question mark for Youtube policy.
He then uploads to mainly fresh channels (I guess)
He uses everything random and has devices, say 5 PC's 5 mobile phones, random browsers, unique IP's.
Videos go viral, he sell account to some markets out there. Pretty much the end of AMA, you gave us no hints buddy.
You download or create videos, upload with unique devices to internet, some video randomly go viral sooner or later, you sell account for $200.
ok
