This is a simple Tampermonkey script that allows you to filter your timeline so that tweets containing certain words are not displayed. Useful to block users' client-side (by restricting tweets containing the username) or annoying conversation topics.

1. Install Tampermonkey Tampermonkey on your favourite broser. This allows you to add arbitrary scripts on your browser.
2. Go to: Create a new script... and place the contents of script.js there, replacing the words "<word_1>", "<word_2>"... by the strings/usernames you want to avoid seeing. Any tweet containing any of these words will be removed from your timeline.
