Long since dead but I put a lot of time into a browser-based (2D) MMO called Nowhere Else and Beyond back in the day.
You could build islands and they'd be placed somewhere in the world for people to sail to, you could create quests set on your island etc. There was even an object inventor for creating equipment.
He's not a well-poisoner, someone just decided to chug from a bottle clearly marked "do not drink".
If someone spends the time to integrate mystery code without taking the time to check the license allows it then frankly they dug that hole themselves.
Because it's great for analytics. The formula of "face in thumbnail, big text, bold colours" works and YouTube WANT you to be clickbaited so that you watch the ads.
RSS is essentially dead, sadly. Can't push ads or gather analytics through it so it's been "optimised out" of the web.
Even those rare sites that DO support RSS quite often only show the first paragraph or even just the title of the page, which I suppose is an acceptable compromise.
