This might be closer to a shitpost but....
Are the bot scammers for this subreddit seriously coded to title their posts "Hello" and "World"?
I have seen low effort spam before, but this is so low effort it makes me think it is actually high effort.
(If you are not in the loop, almost every basic coding language class makes you write code to display "Hello World" as your very first "congrats you coded" assignment)
