How does the proxy ship an item??
Mostly by using trusted third party escrow.
Oh I see.. and what if that third party gets watched somehow, or compromised?
What anon features are built in?
Think of this as a proxy masternode which earns fee by shipping various items to your location. Bad actor intend makes a big difference to profitability of honest nodes. If a malicious node misses a shipping deadline it will be instantly banned by other nodes on the scariest Ghoul network.
