Proof of Usefulness Score
Category Standard

KupujemProdajem is the dominant online classifieds marketplace in Serbia, comparable to a national version of Craigslist or eBay. External verification confirms it generates approximately $11.5M in annual revenue, employs over 50 people, and serves as a primary commerce hub for the region with millions of monthly visits. Despite the submission's extremely low quality (vague claims, incorrect technology listing), the platform's verifiable real-world utility, massive audience reach, and established market traction warrant a high score. The score is dampened only by the lack of insight provided in the response and the randomization factor.
