We don't run internal honeypots and no one has ever been caught in our company, so I disagree. And yes, a reply may be "That you know of...", but considering that we run weekly audits and nothing has leaked, I can be 100% sure of it.
Do you really know for sure though? That is what keeps me up at night. The irony is that one of the leaked screenshots is of an internal security auditing/monitoring tool.
