I hope you’re addressing some obvious issues like the dishonest advertising in the Buddy invites and rewards from other players thread, the slight difficultly in linking peoples’ in-game characters with their entry on your list of past buddy invites to provide them their promised reward, the confusion in which payments provide a reward, and the ambiguity of whether you’re allowed to recruit yourself.
I’m guessing the rewards will be substantially less than the current 500 PLEX / 30 days of game time per recruit which should go towards making those issues somewhat irrelevant.
