I made a user-script that will block twitch chat spam (persona r9k mode, filter caps lock, repetitive words etc)

You can see it in action here (debugmode)

First you will need tampermonkey for Chrome (or similar) https://chrome.google.com/webstore/detail/tampermonkey/dhdgffkkebhmkfjojejmpbldmpobfkfo?hl=en

For firefox you may use greasemonkey https://addons.mozilla.org/en-US/firefox/addon/greasemonkey/

Then you will need the script itself https://greasyfork.org/en/scripts/15556-antikappa-remove-chat-spam-from-twitch-tv/code

Just press Install when you have Tampermonkey and it will run.

You can change the following settings to your liking, within the code itself:

//CHANGE SETTINGS HERE
r9kModeBool: true, //personal twitch r9k
blockUpperCaseBool: true, //removes exclusive caps lock
blockVeryLongMessagesBool: true, //removes long messages which usually contains repetitive copy pastes
blockRepeatedWordInSentenceBool: true, //removes repeated words, like "Kappa Kappa Kappa"
blockTypicalSpamBool: true, //removes suspected random spam
blockNonEnglishCharactersBool: false, //blocks everything that isn't the standard ASCII character set
//CHANGE SETTINGS HERE

I thought this was relevant to the dota2 sub since I watch a lot of dota on twitch. So hopefully some of you will find this useful for your chat experience.
