resisting censorship

When there is a take down request to a pod, instead of just deleting the content, we should provide podmins a chance to send a kind of SOS message to all known pods. Other podmins could choose to keep or censor the same posts from their pods. This will allow podmins from free contries to host censored materials without legal threats and save legal troubles for podmins in countries like India and China. When censored pod gets acknowledgements from other pods, it could show links to other pods who chose to accept the post and there should be an option to set url of anti censorship campain in those posts.
