Spoiler Slayer

Spoiler Slayer is an open source, tracking-free, simple extension for Chrome that blocks TV, movies, and book spoilers on your favorite sites. Subscribe in one click to public lists that always stay fresh and make sure no spoilers slip by, or use the advanced settings to fine tune what text to block on what sites.

Spoiler Slayer includes out of the box support for many popular sites, and it's easy to add more.

Settings allow users to customize the blocking experience with 3 modes:
* Censor - Hides potential content under a black censor bar
* Blur - Blurs out content
* Remove - Removes content completely from the page as if they were never there

Other features include:
* Imports, exports, and subscriptions - Create your list of spoilers or sites and share it with the world!
* Blur intensity - Blur elements on the page to oblivion, or keep them just under legible
* Reveal on hover or click - Feeling brave? Reveal the spoiler when you hover over or click on the censored area
* RegEx support - Anticipate common misspellings or only block certain URLs
* Selector helper - It's easy to add new sites with the built-in selector helper, which highlights items on the page as you type
* Blocked counts - Know how many times you've avoided mild panic!

No data is sent to any 3rd party servers by this extension. Data is fetched when updating subscribed lists, but this is not required for functionality. The extension is aware of the sites you visit so it knows what to block, but it does not retain or transmit that information.
