If something looks like a Pascal's Mugging when it involves ridiculously large utilities, then maybe you agree with me that you should have bounded utilities.

"Pascal's Mugging" seems to be any scam that involves ridiculously large utilities, and probably specifically those that try to exploit the payoff vs likelihood ratio in that way. A scam is approximately "an assertion that you should give me something, despite a lack of strong evidence supporting my assertion". So if you offered me $1,000, it'd be just a scam. If you offer me eternal salvation, it's Pascal's Mugging.
