Trypophobia … definition from Wikipedia.
Trypophobia is an aversion to the sight of irregular patterns or clusters of small holes or bumps. It is not officially recognized as a mental disorder, but may be diagnosed as a specific phobia if excessive fear and distress occur. Most affected people experience mainly disgust when they see trypophobic imagery.
I have noticed a whole series of online ads using pictures designed to trigger those with trypophobia. These mostly featuring bumps on human flesh.
The photos appear to have been created by glueing pinto or black beans onto people’s faces, feet, or hands. I haven’t cared enough to determine what they’re selling, something to do with a skin ailment one supposes.
It is an interesting, sick use of imagery to “hook” those with phobias. I personally find the practice repulsive, an attempt to harness compulsions for commercial gain. Morally, it is about on a par with putting crazy people’s erratic behavior on commercial display for the amusement of those with low tastes.
