How to check your personal game data for banned players

After the new GDPR Changes have Valve Made it's now possible to see who got VAC & Game Ban

How to check your personal game data for banned players

1. Get Ban Checker for Steam browser extension for Chrome[chrome.google.com] or Firefox[addons.mozilla.org].
   
2. Open the page with your competitive matches.
   
3. Set your own Steam API key (this is important, otherwise you won't be able to scan every player) by clicking "Set Steam API key" button, you can get your API key here.
   
4. Now press "Load whole match history" button and wait (and hope it doesn't fail loading). Your browser may become laggy if you have a lot of recorded matches.
   
5. Once you've loaded match history press "Check loaded matches for bans". This will also take some time.
   
6. If there were no errors during any of these steps you now have your match history loaded with bans (VAC or Game/OW) of each player displayed.

Here's 3kliksphilip video talking about it and the reddit post.

The bans are only counted for MM, not wingmans

Total ban stats: 105 VAC banned and 21 Game banned players
Total amount of unique players encountered: 3630.

My personal data doesn't go further than 408 matches but I have 700 wins ingame?

API Requests seem to be working, getting a TypeError when I check loaded matches for bans. Was able to pull all of the request URLs from console and iterate manually, good enough for me. Cheers!
