They have only been doing sea for about 3 weeks, I think; that's about the time when my LS started getting /tell bombed with offers to sell Temperance Virtues and whatnot.
Also to update: they did another JoL last night and apparently got both earrings - Novia selling for 30M, Novio selling for 100M in Batillia bazaar. That's at least 200M worth in under 1 month's time. The RMT LS "Cowboys" that did it still farms sky as well, so they aren't even spending 24/7 in sea to get those results.
