I have spoken to the person in question (a friend of Agony as it happens) and they hadn't logged in to that char for a while.BTW - looks like a one man corp was formed last week to siphon off some of your isk -agony leashed. People are scum.
Apparently a single 50mil payment had been transferred by mistake, which has now been returned to the sender.
The corp was set up as a joke, not to scam people, and I trust the person in question to check from time to time and return anything sent by mistake.
However, if there is one message here it is that like in PvP, attention to detail is key. Be sure who you send isk to and double check contracts etc that seem too good to be true
