Being a scammer doesn’t mean you’re a criminal mastermind.
It takes capital, time, and work to become “the EA of scams”, at which point you’re calling further scrutiny on yourself, meaning even more work (and staff, who you’ll have to trust) to not be in hot water with the law.
Scammers, like the people they scam, are mostly after a quick easy buck. You’re posing “why not” questions as if it’s straightforward to accomplish what you’re suggesting. It’s not. It takes effort and risk without a guarantee of success. Most scammers don’t become “the EA of scams” for the same reasons most game companies don’t become EA.
(I do know at least two real exampless of this meta-approach to scamming: 1. there are meta content-farms, which hire people and train them to run seemingly-independent content-farm YouTube / TikTok / etc channels; and 2. there are serial Kickstarter/IndieGogo scammers, that follow a loop of forming a new shell company, hiring a new actor to pitch a fake idea, steal people's money for it, and disappearing.)
And, while they're at it, why not constantly seek to acquire the pitch+content from smaller, nascent money-making course creators, and run their content through your existing business engine? Why not be the EA of scams?
