Are you so naive as to think the Lego videos were the only thing they've produced? Iran is behind only China and Russia in terms of internet propaganda operations. It's fairly trivial to count the number of accounts on social media that are active every day, but coincidentally not active at times when the power's out in Iran. They operate troll farms same as China and Russia does.
How do you think the Lego videos came out of nowhere and got picked up by the algorithms? Upvoted by the troll farms.
I've seen some strange activity on Lemmy like the exact same content being posted from multiple accounts. Always pro-Iran and anti-Israel.
You're being incredibly naive if you think they just put out some cute little Lego videos and nothing else. You're the target of an information warfare campaign, and it seems to be working. You need to think a little more about what content you'd expect troll farms in China, Russia, and Iran would be producing.
