Not really sure what makes you even think something like that could happen. A regex is far too specific for such things. Morality laws in the Middle East are extremely vague and flexible to apply on whatever. The rules communicated to Amazon are probably in the form of “nothing that’s morally obscene”, “nothing that’s against god’s nature”, “nothing against our culture”.

We were traveling to Saudi Arabia in the 90s with another family. They confiscated their son’s Pokémon cards because Pokémon was satanic. In the 2000s I was traveling to Egypt and the customs officer demanded explain what a book I had was about. The book cover had a sheriff badge on it, and the office insisted that’s a book about Israel. I learned then that you’ll never see a 6-point star in any form in any Arab country because they view it as an Israel/Zionist thing regardless of the context. Last time I was in Saudi Arabia was in 2016 and they held me at the airport because I had a board game called Mysterium that looked kinda spooky. I travelled there many other times without any incidents. It’s 100% luck of the draw on the customs officer you get.

Things like that going to a customs officer who has to open a random package and inspect it have a chance of being randomly confiscated. Certainly anything that even hints or winks at LGBT stuff is highly illegal there which is what this article is about.
