I've read about visiting the DPRK; apparently they won't stamp your passport because they know it'll cause you problems when you leave (back to the states), and for non-Americans, they don't get their passports stamped so they can visit the US without issues; at least I think this was the case, as I'm sure I read about that on a website dedicated to arranging tourist visits to the DPRK.
Wait, those stamps actually effect travel? I thought they were like cute little “hey, you made it!” markers. Like a collection or something, I didn’t think you’d be penalized for having a stamp from a “bad” country…
I will admit I don’t travel much, like, at all so I’ve never really experienced this. I’ve been questioned once before but I think the guy was just making conversation. I was visiting the states so maybe less suspicious than coming back from a non-friendly nation…

AFAIK certain countries, like Indonesia, raise an issue if you have Israel stamp. It should be expected that a place so hellbent on everyone following their arbitrary rules as USA would also cause issues if you have a stamp from "bad country"
