/prog/ userscript

it occurs to me that it should be possible for userscripts to do "collaborative moderation" on a website:

* use a userscript to add an (ignore) link to the header of each post. clicking it will add the post to the localStorage ignore-list and thus hide it.

* use ignore >>1,3-4 reason to signal to others that you've ignored those posts (and why).

* clients can decide for themselves what do if ignore directives are found in a thread (tentatively use, pop up a dialog, check tripcode... whatever)

could someone write this for us?
