This is an interesting topic.
I'd like to say that I'm above getting upset by what people say against me here, but tbh, sometimes it does get me all rattled up etc.
It's almost worse when you get critiscm on a board/forum if you know what I mean. You're being judged on your ideas and words, which are important to me etc.
Usually though, I do take it with a pinch of salt.
Yay!
I would say that people do seek approval on forums becuase of exactly that, you are being judged on your ideas and words. And everyone would like their ideas to be liked and excepted and thought of as good etc.
