Better they add trade permit on bst shop or any shop with 5days to complete, can buy material item everyday for trade permit , so bot can no longer instant transfer of items and gold. Ed team have time to banned bot before getting millions of stealing income from the game. Also add trade permit on f11 via cc. So p2w players can have option. Novice guide is useless for trade permit nowadays. Guild items storage for members with non novice must be restricted too.
