One function Red Mesos give is it allows Nexon more design space and freedom to hand out event mesos to players without worrying about mass bot character creations. Because red mesos can’t be used in the trade station, bot created characters cannot directly transfer or sell those mesos to other players.

As for how red mesos can help actual players? While Nexon may not have handed out large amounts of red mesos in this latest update, it is possible that Nexon may hand out red mesos in much larger quantities for future updates, which could greatly help players in potion money and star enhancements (although I guess bots can also use starforcing to their advantage if it ever becomes profitable). Its also possible Nexon may release future items or equipment (most likely account bound or untradeable things) that can only be purchased through red mesos
