well, they r kinda like pimples
one, if you have dirty hands, ur just spreading bacteria onto your face, possibly making your pimples/blackheads worse
two, when you sqeeze its unlikely you will get all of the stuff out - hence some is left there and can grow making it look worse
and three, when you squeeze, apparantly, although some stuff may come out you are actually pushing the gunk further down into the skin creating a deeper wound and a longer and probably worse looking pimple
also you'll just be all red after it - not a good look
