Alright this might have gone around but here is what converstations that I just had with two SE reps and their supervisor to verify.
For those that have lost multiple items here you go.
They will be restoring items that are thrown out, sold, etc in the game logs they have. So they will be restoring any lost items that were lost and they can track it in the game logs.
I also asked about the 1 item per character policy. He stated this is the exception. If it's in the game logs as lost; it will be restored.
I asked what about if they sold something on the AH on another server/or current server for example "Bone harness+1" was the example I used (don't ask me why hehe). He said no items will be taken back from players that bought said item off AH, BUT a GM will restore said item to the player IF and ONLY if it's in the game logs.
SERVER Restoration.
When a player regains access to his/her account, you can apply for server migration "FREE OF CHARGE" to the orgainal server that it was previously on before the compromised account was taken from orginal owner.
Sorry didn't ask about any gil related restoration but here hope at least.
Sorry for grammer trying to get this out as fast as possible.
