How about the fact it seems that Sweet Bro and Hella Jeff could based off of John and Dave, for example the numerous SBaHJ tiers in John's echeladder (You are the star, It is you, Unreal Heir, etc.)? And then Davesprite also used the "ahahaha you fucked up" reference when John was writing his letter to the trolls and dave and rose?

Yeah, possibly.
