You must be new here! <3 In FFXI we had alliances of 18 level 18 characters with no subs forming a train to farm Yagudo Necklaces in Giddeus. I don't think a one of them got punished until they were actually caught botting.
More importantly: Who's buying gil for FFXIV? The stuff rains like candy from the sky as it is. You get gil just for doing the things that get you Exp/Sp and treasure: Behest, Leves and Raids. It's like you get paid to level up.
