Not sure if this is the right place to post, but be gentle if it is wrong

I had a pf up buying eso mats for gil, and someone told me that I could get reported. I was surprised given that I see a lot of pf up buying eso mats and the fact that historically people used to do this for soldiery, myth and philo (cant recall) and I have never heard of anyone being banned for it.

While I understand people getting warned for selling fantasia potions and other mog station gift codes for gil and the recent amazon summer codes, but it is surprising that people using their esos to buy eso mats and selling on the marketboard would be that much different to a buyer requesting to buy eso mats on pf for gil
