I would argue that this should be the course of action no matter who the account is. Frankly there is enough info here for the resident autists to dig this up as it is. What is more important is the behavior of the person in control of the account.

This is one of my primary grievances with the culture of this forum. If you are right you get to feel good about yourself and tell everyone how great you are for preventing scams, raising your own profile in the process. If you are wrong, oh well it costs you nothing to seriously invade some ones privacy, disrupt their life, income, and possibly burn their reputation. No skin off your back, so fuckem right? I have hockey pads, I can be Batman too!

This mentality is exactly why systems of due process exist in law, and exactly why Theymos made some of the most recent trust system changes.
