In a sincere way before I begin speaking, attacking people should NOT be the way, it doesn't make us better people than them if we begin harassing.
Now, I looked about what this fellow posts, and there are worse things to point out about them uhh. I would rather suggest blocking them if you're uncomfortable or reporting anything that breaks actual community rules (which Aktan might actually have broken by what I'm finding out), but there's no good reason to go out of your way to harass anyone because it doesn't make anyone a hero, it just creates worse problems down the line and can even put you in actual danger.
