Like you ask a question and someone comments "I've never heard of that" or "I don't know what that is" or "I'm not sure" Or they say something completely unrelated to the question because they don't know the actual answer. Thats one of my biggest GaG pet peeves
Yes because when I browse questions here and if I totally have no idea what to tell the asker I wouldn't bother to answer. Obviously 'I don't know' or 'I am not sure' isn't an advice or opinion. It just an ignorant phrase which gives them the Xper point. You aren't helping at all. Just stay away from the questions.
Nope because small things like these just don't annoy me. It's not enough to annoy me
Yes. I downvote them for being useless and make a mental note not to talk to them. They're probably only concerned with spamming answers for the xper. UNLESS they say that they don't know, but offer a bit more advice or suggestions.
