I am not really sure how it could be faked. The fake assurance, in order to work, must be connected to you.

By default you could choose not to trust. If you don't trust random strangers it's OK. So I don't see how it would damage someone's reputation worse than today.

It would potentially only add trust. Arguably, today we have bots because we have no other option than to trust without justification. With the public social graph, the trust above the baseline would be justifiable.
