Gaining karma on accounts are a PIECE of cake with unmonetized media. The hard part of cracking Reddit is the monetization part. If you have a post that you boost with 100 or so upvotes and is informational content with no purpose to downvote, then Reddit users will follow like SHEEP and upvote as well.
However, if you have a promotional material that you are promoting with Reddit that you boost with upvotes but has stuff that is obviously a promotion, then people will obviously report/downvote.
I'll consider you king when you get 4 digits in sales with a promotional post on a subreddit with around 5-10 fake upvotes. Until then, I'm the king of Reddit in my world
