The Steem blockchain does allow arbitrary JSON to be included as metadata with each post/comment. You can check it out by viewing the post with steemd.com or steemdb.com.
Anyway, this proposal is old. And although there is still no moderation functionality on steemit.com, it is in the pipeline with the Communities feature, which I am really excited about.
Can you point me towards a post about the communities feature moderation, and where I can read more about the JSON metadata?
I'm trying to learn more about these discussions, but not sure where the best places to discuss these things.

You can use steemdb.com to view the raw data of a post and explore the different ways the JSON metadata is used by clients. For example, here is a link to the raw data for your comment. Scroll down to the
json_metadatafield. Notice that ChainBB reported the app/version in theappfield. Also a field specifying theformatof the content and an array oftagsfor the comment are also included. There isn't any official documentation for how JSON metadata should be used (it is not like it is enforced by the blockchain anyway), but various unofficial standards seem to have emerged, mostly by following the usage led by the steemit.com client.There is a draft spec available for the Communities feature in the wiki of the Steemit Condenser repository. Keep in mind that this is just a draft and things may change with the design.
