It would be nice to have:

1. a white list to disable the extension on specific websites,
2. a black list to enable the extension on specific websites,
3. both 1 and 2

This sounds like a great idea to me, but to be honest the motivation is actually issue #2.

When I'm browsing in a website that includes some source code examples, all code snippets which include the word constructor appear hidden due to this extension. The weird part here is that this happens even when "constructor" was not added to the Blocked Words list.

Steps to reproduce:

1. Install the extension on latest chrome.
2. Add example list from the options' placeholder: star wars, skywalker, game of thrones, jon snow, lord of the rings, bilbo
3. Open some web page with code snippets on it, like the angular tutorial.

• Expected result: as no words from the blocked words list appear on the page, nothing should be hidden by Spoiler Block.
• Actual result: constructor() { } line is hidden by this extension.

This also can be reproduced in:

• windows 10 and Ubuntu 18.04.2 LTS
• latest chrome and latest opera
• normal browser window and incognito mode

I've been digging into the source code briefly and I haven't find the piece of code responsible for this behavior.
