an extreme or irrational fear of or aversion to something.
"Extreme" and "Irrational fear" are the key words to a phobia.
Trypophobia is a hard one to pin down, because it would be expected that most people be disturbed with such imagery. It's not an irrational or extreme response, it's something that tends to be expected, particularly with the more insensitive images that tend to plague google images around trypophobia. The more tame examples that google images gives of trypophobia are the lotus seedpod displayed earlier in this thread, the "pits" along the surface of strawberries to hold their seeds, and bee honeycombs. -- If you google image the rest you'll get much more grotesque, often photo-shopped examples that are trying to evoke a disturbing response from the audience (A response that would be expected, thus not irrational).
Regardless on whether "Trypophobia" applies. Those images were not okay.
