I'm not exactly sure the whole situation only that you transferred your friend money using their in game feature. From my experience, transferring funds to a friend is fine. Transferring funds and then playing on the same table is usually not accepted. It would look like collusion pretty easily. Even if you lost money doing it.

That may not have been your intent and may not be how it happened. In the future I would suggest if you want to play with a buddy that you have them have their own wallet and make their own deposit from it. You will save yourself a headache.

Regarding the accusation of fraudulent activity, seems pretty unlikely you were colluding or you were very bad at it lol.
