A CMU peer-reviewed study found 6 million fake GitHub stars across 18,617 repositories, with stars openly sold for $0.03–$0.85 on Fiverr and Telegram. Venture capital firms explicitly use star counts as sourcing signals, creating a $0.06-to-$10-million arbitrage that has built a mature shadow economy. The FTC's 2024 rule banning fake social influence carries $53,088 penalties per violation.
