This extension will add a badge list to a steam profile, showing information such as Trusted or Scammer.
This extension is aimed at providing useful information specifically for trading within Rocket League.
When visiting a steam profile, it will query the database for that user's ID. If that user has any entry it will then edit the page to display a list of badge in the right-hand side-bar. At the moment there are 4 badge: Extension Developer; Trusted MiddleMan; Donator; Scammer. Anyone with Trusted MiddleMan is safe to use, and anyone with Scammer is unsafe to trade with. (Donator does not mean trusted.)
If there is any confusion as to what a badge is, you can mouseover and it will display a tooltip to explain.
