They don’t need a strip search to see you have a spoon in your underwear with the scanners they use these days. They can tell what kind of genitals you have in your underwear and which way it’s tucked (at least they are technically capable of showing that, they might have pulled back from that due to the backlash about how much they could see). Spoon in the underwear is a specific signal to let authorities know someone is being trafficked and can apply to sex trafficking or kids being brought to countries where they can be married off into an arranged marriage. Not sure how it would work if the parents want to emigrate to Russia. Also not sure how thoroughly they block the arranged marriage thing if both parents are on board.
