My Understanding of Trolls

I was never really aware of what "trolls" were until now. I also didn't know that, that's what those who are harming others through a computer screen were called. When I think of the word troll I think of the little ugly dolls. Now that I have a full understanding of what these types of trolls are it makes me sad that people actually have the audacity to say cruel and unnecessary words without saying it in person. In my opinion, I feel like we will never be able to get rid of these types of people even if we report them and their accounts are removed indefinitely. Reason being, is that the internet is just getting started and there are millions and millions of people who have accounts on different websites where they are able to write, comment, and post whatever they'd like, there are so many accounts that it seems to be a difficult task to remove those that are being harmful towards others. Sure, there are many ideas and ways that are happening right now to remove these accounts but how long would it last and won't people find other ways to still be a jerk through a screen? I have social media accounts and honestly I've never seen any type of "trolling" or maybe I do but don't think of those people as "trolls" but another label.
