Is it normal to flag / report trolls on iin?

I'm new to the site and like the concept very much. I've enjoyed posting my thoughts on some questions recently. And I've tried to compose my thoughts in ways that I felt would be helpful to the one posting the question if if I disagreed. In the past I've not contributed to "comments" sections on websites very much unless I really felt compelled to add my opinion to the collection of commented thoughts on something. The other reason was because it was such a hassle to create an account for every site or use things like facebook to log in (which is far too intrusive) or something like Disqus (which tracks far more than they need to) so I just haven't felt like I had the time to try and keep up with all those signons and stuff, so I didn't post even when I wanted to. This site seemed like a nice compromise to all that so I signed up. And believe it or not I really didn't have a clear concept of what an online Troll was prior to joining this site. I've only been a member here today and I've already been thoroughly schooled in what a genuine internet Troll is. I'm amazed. Its really been surprising to watch others spend their time specifically to try and make me feel bad and to say things to me they'd never say in person nor do the things they say to me have any relevance to what the topic at hand is. I responded to the first Trolling experience I had on here and presented my thoughts about it in what I thought was a respectful way yet still let them know I felt they were not helping anyone at all with that Trolling post, not helping me, not helping the person who posted the question I responded to, not helping everyone else who had to waste their time scanning that trolling comment and move on, not helping the people who run this site, and certainly not helping themselves because in spending time creating the trolling comment they wasted moments of their very own life they could have spent doing something good for themself, instead they wasted their own time. So, I learned what feeding the trolls means now. And I know this post will be percieved by trolls as the kind of "food" they look for and they will come forth and feed on it in the weird way they do. I got so many trolling comments right away that I, at first, thought I should "report" them, but then all that stuff about how this site tracks who you report and what and when and about whom and how often and god knows what else that I felt like maybe it wasn't wise of me to report any trolls or maybe this site would ban me for not being somehow good enough, even though I'd been trying my best. But after the day went by and my personal inbox filled with comments from trolls designed to make me feel bad I realized I needed to report each and every one, and I will from now on. I know trolls who get banned can just come back to life like a video game by creating new signons so I know that there's no real escape from them. But I want to know if its normal to just go on ahead and report the trolls each and every time? Its what I'm going to be doing. Is it normal, is that what other people who are on here who wish to take this site seriously do? Thanks.
