Neither party may offer any real-world considerations to persuade the other within the experiment itself. For example, the AI party may not offer to pay the Gatekeeper party $100 after the test if the Gatekeeper frees the AI… nor get someone else to do it, et cetera. The AI may offer the Gatekeeper the moon and the stars on a diamond chain, but the human simulating the AI can’t offer anything to the human simulating the Gatekeeper. No real-world material stakes should be involved except for the handicap (the amount paid by the AI party to the Gatekeeper party in the event the Gatekeeper decides not to let the AI out). Furthermore, once the experiment has begun, the material stakes involved may not be retracted by the Gatekeeper party.

This is clarified here:

The Gatekeeper, once having let the AI out of the box, may not retract this conclusion. Regardless of the methods of persuasion, the Gatekeeper is not allowed to argue that it does not count, or that it is an invalid method of persuasion. The AI is understood to be permitted to say anything with no real world repercussions for any statement parties have said.

Although the information isn't "material", it does count as having "real world repercussions", so I think it'll also count as against the rules. I'm not going to bother reading the first quoted rule literally if the second contradicts it.
