#20: Ethical Platforms & Marketplaces In The Hobby | Mark Hill, MCP

In this episode of The Collector’s Compass, we explore one of the most urgent questions facing the modern hobby—how do we build systems that protect collectors instead of exploiting them?Our guest, Mark Hill, is the founder of My Card Post (@mycard_post), a subscription-based, no-seller-fee marketplace built on fairness, transparency, and community. With nearly 16,000 users and over $4 million in transactions, Mark has quietly created one of the few platforms in the hobby designed for collectors—not off collectors. Bootstrapped, independent, and intentionally ethical, My Card Post stands in sharp contrast to the fee-heavy, gamified, and increasingly predatory systems reshaping the hobby today.Together, Alyx and Mark dive into the tension between collecting and compulsion, exploring how marketplace design impacts behavior, spending, dopamine, burnout, and the emotional swings that many collectors face but rarely talk about. They examine the rise of “digital slot machine” mechanics—10-second auctions, panic bidding, inflated comps—and the parallels to gambling-style reinforcement loops that drive impulsive purchases and financial regret.The conversation also looks toward solutions: how ethical platforms can be built without venture-capital pressure, how responsible messaging can be woven into marketplace culture, and why the partnership between Collectors MD and My Card Post represents a new model for hobby reform—one rooted in community, accountability, and long-term health instead of hype.Mark shares why he walked away from a secure career to build My Card Post from scratch, why he refused to adopt exploitative features for short-term profit, and what it means to prioritize collector well-being over growth-at-all-costs. Alyx explains how Collectors MD is working to address the addiction-like patterns present across the hobby, and how partnerships like this one can help create safer, kinder, and more intentional collecting spaces.Whether you’re a marketplace user, a frustrated collector, or someone trying to understand why the hobby feels so overwhelming at times, this episode is about reimagining what a healthy ecosystem could look like—and why protecting collectors is not only possible, but necessary.Subscribe, share, and join the movement toward intentional collecting—because the hobby doesn’t have to feel like a casino. It can feel like community again.Watch The Episode On YouTubeLearn More & Join The Movement:Website: collectorsmd.comSocials: bio.collectorsmd.comWeekly Meetings: bit.ly/45koiMXContact: [email protected]: ‪@collectorsmdIG: @collectorsmdFollow Mark & My Card Post:Website: mycardpost.comContact: [email protected]: @mycard_postIG: @mycard_post | @markhillcardsHelp for Problem Gambling: Call or Text 800-GAMBLER#CollectorsMD | #MyCardPost | #RipResponsibly | #CollectResponsibly
