The problem with this is that you have willingly let others use your account, chances are good one of them for some reason did this to you so i would not count on getting anything restored. By giving your account details to others you have willingly compromised your account and anything done by these people would not justify any restoration to the account.

This is my experience from other games, with so many having access to your account it will be almost impossible to prove you have been *ed.

I still do hope you get your things back, but i would not put to much hope in to it.
