Twitter stays interesting only if you constantly follow new people and unfollow users who start flooding your feed with low quality content.

However it can be hard to keep track of the track record of each user and so one ends up doing a trigger finger approach and unfollows on the first low quality tweet.

This helps change that. By appending a voting system after each tweet, you can privately keep track of how many down and upvotes you have given to the quality of each users' tweets.

You can use whatever threshold score you want to draw an assessment of what kind of action you'd like to take.

The votes are stored in localStorage via GM_set/getValue and don't need access to any remote server.
