Not sure where you got that from; some of the images were fake, yes. Quite a few were real. Pictures of maggot infested wounds, and pictures of a dead fox with its entrails open to the air on the ground. All spammed over an hour period.
Well, no, because it's not innocuous. It has a smell that is unpleasantly overpowering. Trypophobia isn't to do with explicitly gory images, though. That's the point. It can be with innocuous things with neutral connotations.
At the moment. It's a very poorly understood state, so while you can sit there and belittle people by saying 'it just grosses people out', there are those who are genuinely affected by it in a debilitating manner. Maybe show a little understanding that not all people feel the same way you do?
