In each case, your answer was essentially, "the disgusting thing in its entirety!" This is equivalent to nudiustertian's reaction toward the affiliate site.

The difficulty comes from trying to zoom in to a higher level of precision, as nimchimpsky requested. What exactly do you find disgusting about someone eating an eyebrow, for example? Can you explain it?

Yeah, it is disgusting that someone would eat their own hair (people die from that because it clogs there intestines). Same with POOP/PEE + smell - it's gross because it literally IS gross.

Yeah, there's an evolutionary cause for sure. Maybe the cause for revulsion at certain kinds of marketing is a similar protective mechanism but driven my memetics rather than genetics at the core.
