To start off this community, here are some Youtube links for channels that contain some great popping.
SacDepSpa - Lots of different types of pops here. Mostly blackheads and focusing on the head and neck areas. Close up views.
MrPopZit - A dermatologist, that has different types of pops from all over the body. Abscesses, blackheads and other types. Some videos can be tedious.
