Propulsion was trading with this person (ironically from a thread that originated in the currency exchange section - it not in the alt coin marketplace section - the same section you originally posted this in). He was also trying to buy trust.
Uh oh, it looks like whoever did hack the account actually was doing trades...shit. Not good. Xetsr can you please leave negative trust for the account? It looks like you are on default trust.
