How to deal with this kind of friend?

[Kassiekane]

So I invited one of my old friends to this game.

He was playing FFXI up to this point, and wanted to play FFXIV. So I said, okay come to my server and we'll get started. Well, he went to the wrong server, and made a char there. Whatever, I made a char there too and we started playing.

So we was in the process of sneaking to Mor Dhona so he can preview the high level gear on his character. However, before we even started he was talking about how he bought gil on his character in FFXI and he's rich because of it. I should've raised a red flag there, but whatever, we started our journey. Along the way he was stopping a lot, and by the time we got to the Cerulem Processing Plant, he asked me "Where is the moogle" and I pointed it out for him, and then suddenly has 2 million gil on a level 2 character that hasn't even unlocked Return yet.

The worse part is that he plans on making a character on Lamia, meaning he's going to buy EVEN MORE GIL. What do I do!? I want to play with him but I don't want him on this game if he's just going to ruin the game like that.

Edit: I decided to just leave him alone. Hopefully SE will detect his suspicious income and confiscate it. Seems pointless to invite a friend to a game just to make him leave.
