I farm. Probably too much, too many hours, and too many weeks now.
I've helped non-farmers by PL-ing their soon-to-be-a-farmer toon, to 50, so they can get started doing it for themselves.
I've offered advice on my build and how much it cost me (Tullus, Indomitable; 2 billion+ infl).
I've given away tons of influence to lowbies and new players (as I was given influence as a lowbie), and told them to Pay It Forward.
But I would never imagine selling my farming services for RL money!
Good on the Devs for catching these thieves (because that's what they are) and banning them.
