Being rated as "Dumb" does not really mean you are being hated.It either means, that one of your post's make no sense or just contribute nothing at all to the discussion (if it would contribute nothing at all to the discussion it would been most likely get removed by a staff member).Leaving the community just because of some "Dumb" rating's is just...meh.You see, these are all just internet points, worthless.Just like Reddit's karma system (I do believe you could sell like a million karma for money...but really low amounts of money).I'm not really receiving any kind of negative ratings or hate (but I do get alot of "Bad Spelling" ratings alot recently for like probably 1 spelling or grammar mistake in a post) and you should never take negative ratings (or positive ratings for that matter) as a reflection of how people think of you.
