This monster didn't understand the rules himself. Although the exchange is a bit cunning, it is still within the rules, no fault. To give an example, everyone is boosting trading volume, and there are rewards for the top one thousand in Anan, while BG might only have a hundred (no malice, just stating facts, please don't criticize). Therefore, participating in the activity doesn't mean there are guaranteed rewards; they have quantity restrictions. Finally, I express my personal opinion, which only represents myself; I basically do not participate in BG's activities, as I am self-aware and cannot make it onto that leaderboard.
