SleemanMan: Now the question : once an account is closed, do Private Messages still get received through emails ?
There are at least two states of "closure", so the answer may depend. Furthermore, an account may simply be left by it's owner, leaving all functions intact but unused.
Usually, accounts are blocked, e.g. after T&C violations. Then, the user can no longer log in, and you won't find the name in the "WGT Player" search. But if you know the profile URL, you can still access it. That way, the blocked player continues to serve as a count for advertising business.
In these two cases, I suspect that PMs will be forwarded to the email given in the profile (if any).
Accounts might be deleted, perhaps on request of a player. Then, there's no way to find him or to notify him. You wouldn't have a handle for a PM ;)
In general, fraudsters won't apologize. The bitter taste is with the victims :(
