I like the Warpcast Block API.

Block has strong signal than following.

You can build many things with it, such as seeing who is blocking you, who you are blocking, who is blocking him among your followings and viewing the global block list.

I have added a feature that allows you to see anyone's block list.

I will block as many spam accounts as possible.

I think there would be interesting use cases to have the info on bot % for fids too
