This is not meant to be a popular node, but I beg your people to keep this post, and allowing opposition as long as it bear truth.
Very often, people post answers that are wrong, I hate that. Although this is not altogether avoidable, because of different levels of tech background, but at least be nice not to answer questions that one is not familiar with.
When some of us came for XP points, most only came for question and answer. Please leave those people alone, and don't play XP games on them. There are plenty of opportunity for XP point, but restrain yourself to only provide correct answers, even duplicates would be fine, at least confirms the correct answer, and at the same time gain some XP points. Harmless at least.
