If we gossip this information, we may see different values for the same node, and I'm sure someone will propose a "proof who is telling the true" for this. I don't want the reputation we end up with to be gossiped to our peers. In my last research on this, I noted that some nodes with Tor have a completely unrealistic vision of the network. They believe that other nodes are offline, but the problem is actually the overloaded Tor network. Cheers! Vincent
