Beginning in Q4 2025, thousands of customers reported severe delays—some orders from early 2025 still unfulfilled. Customer service became unresponsive. Social media filled with screenshots of automated replies and deleted support tickets.

OppaBiz started as a fan-driven platform designed to help international K-pop fans purchase albums, merchandise, and concert tickets directly from Korea. By aggregating pre-orders and using local addresses, it offered lower shipping costs and easier access to fan club-exclusive goods. Over time, it expanded into photocard trading, group orders (GOs), and event crowdfunding.
