I did that on reddit and it was pretty fascinating to see that some people really can be assholes one day and then be helpful and friendly the next, I would’ve never noticed had I not blocked them. I agree with you though, if someone acts like conversations on the internet are a place for them to vent their anger then I want nothing to do with them.
You could’ve just omitted that part, you know. It makes you look like a giant douche and makes the discussion less civilized.
