A while back I shared a "data leverage roundup": a file on GitHub providing links to support "collective action that involves withholding, deleting, manipulating, and/or transferring data".
It's now a website! https://www.datalevers.org
The plan: to collectively curate a set of tools for supporting -- or stopping -- the flow of data. Later on: also summarize empirical research and have an FAQ.
Current version is in construction, and really just a starting point. Seeking any and all feedback!
