Striking how much downvoting on comments with links to more facts about the genocide is going on here. Striking, but not the least surprising...
I don't if the troll farms and download brigades are limited to China/NK/Russia. There are plenty of mercenaries out there that you can hire.
It takes quite a bit of legitimate activity on HN before your account becomes eligible for downvoting other users' comments. I'd say the downvoting drones are regular Turkish HN users who simply side with Erdogan's policies on the topic and considers censorship an acceptable political tool.
