"This extension will block certain annoying users from appearing in the Activity column in TweetDeck.
Twitter power users [...] often use TweetDeck and follow a good bunch of people. While we're interested in people's tweets, they may be filling the Activity column with useless content such as nonsense favs [...] or massive follows.
Without this extension, you'd need to either unfollow the person who's executing the actions (follows/favs) or block/mute the receiver of these actions one by one. Since that's way too much work, I made this free extension so you can mute these annoying individuals' activity while still being able to read their tweets."
Someone made an extension for this already. Unfortunately it doesn't work anymore and hasn't been updated since 2015.
