I spent 5 years off Reddit and everything then tried to come back like a year ago. I found that even if someone hides their history since Reddit is selling all it's users out all you had to do was go to a search engine and type "reddit /u/theirusername" and you'd find loads of things.

Eventually I realized instead of spending my time researching assholes so I could comment linking all their posts where they made contradicting claims to be a doctor, historian, velociraptor tamer, gay black woman, transgender Danish leprechaun, 15 years old, 40, and retired so I could point out their bullshit and win at the internet... maybe I'd be happier just going somewhere with a smaller shit pile.
