I troll: is it morally wrong?

I confess that I love trolling. The reason I do it is because I write stories, and I like to see people's reactions to the situations I create -- mostly non-controversial, "slice of life" situations like someone fighting with their friends, falling in love, feeling insecure... People give very different advice and it helps me have points of view I never would have come up with alone for my stories.

However I notice people hate trolls, and sometimes I wonder if it's wrong of me to make people answer a fictional situation as if it were real life, because occasionally a person will really pour his/her soul into an answer and in reality, well... it's all made up.

What's your opinion?

p.s: and what if this post was a troll? ;^)
