You should’ve just reported the topic to the moderators, they're the ones who decide if it’s off-topic.
The moderators must have seen them and didn't take note of them. Or the moderator might not be sure if they belong to the board or off topic
It might look identical but the two topics are talking about different things. The first one is talking about road accidents caused by sleepiness/drunkeness and the other is talking about laziness, and sleepiness might be caused by some kind of health problems.
If you think both threads are off-topic, you should report them.
I am not so much concerned about the content of the posts. I think they belong to off topic but I am not that certain about it. That is why I brought it here so that on a broader note, someone could tell me the difference between off topic post and these type of PS posts.
