Is there anyone out there willing to accept payment for building a new feature in Mastodon?
In particular I want to enable server-side filtering of boosts where the boosted post is already available in the timeline (whether it has been viewed or not). From what I can guess, the feature just needs to check to see if the poster of the boosted post is being followed by the user and if so, suppress the boost.
If you're interested in creating a patch for this and preparing it for submission upstream (I'd handle pushing it forward but would apply it on my own server in the meantime), please get in touch.
