You have definitely seen some variety of hot glue that doesn't match anything in my experience. The kind I use doesn't come close to being able to "migrate".

When I say "hot glue" I mean the kind that comes in clearish/whitish finger-sized sticks and gets extruded through a hollow heating element, coming out as a skinny thread of sticky squishable plastic with the approximate consistency of gel-style toothpaste. It quickly cools to a slightly pliable solid form, sticking to whatever it is contact with. When hot, it does not flow into cracks; one would have to force it there intentionally as if spackling a hole.
