A few examples include s*x questions on askreddit, “this” comments, nolife powermods, jokes being more frequent than actual answers
But why clutter up a comment section asking questions you could answer with thirty seconds on a search engine? I understand the annoyance. You shouldn’t rely on other people to educate you on things that literally anyone with internet can find out with very little effort.
If it’s relevant to the discussion, that’s different, but too often it just sidetracks things.
