Ah I see. So the content will still be there as long as people store/access it, but you can filter it out by subscribing to filter-lists? Got it, thanks.
Can you also filter out certain content (by means of hashes I suppose) that you don't want to personally host (not even as partial chunks) but allow everything else?
To the second no: In Freenet 0.5 there was a plugin for that, but for 0.7 this has not been written yet.
You can write that, but you cannot check what exactly it would block. Whom do you trust to censor you? The devs cannot make that judgement. And who will control the censors? You would need a list of all chunks to block (by their routing key).
