Banned from Reddit 6 times, he built a tool for it — and sold it on X: $360 in month one

Arthur Yuzbashev · MediaFast

Arthur Yuzbashev's first two products died on Reddit: six bans, one BuildFast sale. He tracked what had triggered each ban, turned that into MediaFast — a tool for marketing on Reddit without getting banned — and sold it by sharing the story on X. Month one: $360; by January 2026: $5,400.
