I know they're working on tightening restrictions on signups to make them more organic, for starters. But as far as a steem-wide effort, I haven't heard of anything other than vigilante work. A lot of us are out there trying to scrape up the algae at the bottom. I have a "stupidcomments" post, and I tag spammers (or, give noobs a link to how to comment so they can create positive feedback on here). But other than the small users out there like me and a few others I know, I'm not seeing a combined effort yet.

I have a couple of people I'm thinking of getting together with to make it more of a thing.
