This is a GreaseMonkey-compatible user-script that reveals spoilers on the Pawoo website automatically. It should work with all parts of the site, both the main deck-style application and when browsing individual profiles and toots.
Toots that were automatically revealed will have a red-tint behind them.
This script makes use of some modern browser features, so may not work with older browsers.
Specific features used:
The ES6 class keyword
Static class methods
Rest-parameters for functions
Spread-syntax for array literals
The for-of loop
The Set built-in class
The MutationObserver built-in class
String template literals
CSS3's ::before syntax
Almost all modern browsers now support these features.
