I would farm at your own risk, I am not really sure if they would or not, ask this on the aeria forums.
Ask on aeria forums? lol. Probably not a good idea.
But they really can't ban you for "farming s/d." They have no proof at all of what you are doing in a room is for farming your s/d. If they do somehow ban you for that, you can mention they have no proof in your appeal.
