So, let's say someone tells a story about getting reprimanded for carrying disallowed materials into one country or another. How does that help you? It may not be a country that you're planning to visit. The customs regulations of that country may have changed. The person telling the story might have been lucky to meet a lenient customs official. I think you'd do better to check the most recent customs regulations of whatever country you're planning to visit and pack your bags accordingly.

... Unless, of course, you like to read stories about people getting caught and punished for smuggling p0rn. Now that would be truly bizarre.

FWIW, I know someone who was held up for a day at a border crossing in Nicaragua in the 1980s because some people on the same bus were transporting pro-Contra literature (Haha "pro-contra"). He was interviewed and released after several tense hours. The folks with the pamphlets were denied entry. Not terribly thrilling, I know.
