Blocking content is done on a higher level: on the level which links are shown. The default bookmarks only include links to safe content and the core communication tools (Sone, FMS) have decentralized moderation with which people sharing horrific content get blocked without creating centralized power structures. If you see something you think should not be there, you block it, and it disappears for all who trust your judgement. And yes, it took a lot of work to get to this point. The advantage here is: as soon as no one accesses that horrific content anymore, it disappears. So this moderation actually removes horrific stuff. Because the original Freenet is not actually for perpetuity: when a media file is not accessed for a month, it is gone.
