We're all human, have a good side and bad side. Sometimes people "act different", if you know what i mean, in social community, forum, etc to get "popularity". But it's not healthy in my point of view. Just like yourself, behave like you always do in your real life. If people don't like you, they will give you critics, but will that critics it can make yourself better. If you act different from your usual self, there is no use, you can't get any good social experience, because that's not you.
