Maybe I’m out of the loop. Are they bots? People just meme-ing? Perverse shut-ins? Mentally ill persons? It seems like even the most horrible posts (such as one involving the death of the image subject) will have numerous comments to the effect of “Oh, I wish it was me!”… and the most impossible and fantastic depictions have comments that claim or imply experience in a matter-of-fact way.
So, for starters, welcome to the internet.
Second of all, you saw a post depicting the death of the image subject, considered it horrible, clicked on it, then stayed on the page to read the comments. You could have stopped at any point, but you didn’t. You don’t have much leg to stand on.
