Whenever you aren't the target audience, you can't assume that what you've seen is a random sample. Presumably, you were the target audience for whoever was showing you those videos of people doing irresponsible things.

I use it sometimes and most of my feed is just funny commentary by people in similar life situations or who have similar viewpoints. I'm sure there are people doing irresponsible things, but I just wanted to chime in and say that it's not strictly for hooligans.
