I read this comedy website a lot, and they ran an article about the psychology of various stereotypes of people you see on the internet, One of the entries was about trolls, and it linked to this step by step video guide for making trolls give up, every time.
I was pretty skeptical at first, because people always say it's best just to ignore trolls. But I found this vid very compelling. It made so much sense and made me feel like I really understand trolls a lot more. So I had to try it out. Every time I have so far, it's worked. Feels nice to be able to put someone like that in their place and stop them from being deliberately anti-social at the same time.
So anyway, watch this video and never get trolled again.
