For anyone reading my profile page for whatever reason and wondering why I have 100% Achievements on some games- I didn't do that. On September 10th, 2016 my account was stolen for a brief time before Steam Support came to help take my account back, and the guy who took over my account just unlocked a million achievements for no reason (among a couple other things they did as well, which included blocking all my friends and adding their own).

It's stupid.
