I've been trolling on this website for years
Why have you been trolling here for such a long time?
I believe it's something fun to do with my time
It's wrong to troll others on the internet.  They are trying to enjoy themselves and/or to find out useful information, and you are needlessly antagonizing them.  You wouldn't want to be treated that way by anyone in your life.
It's fine. If I don't like what people say here, I just ignore it.
That's fine for you, but you might be making other people upset with what you say while you're trolling. Maybe you should take a break from trolling and see if you feel better about yourself, and maybe you'll realize you don't need to troll so much.
