To get them a real ban, I think you'll have to build a case against each individual user. Back when Yobit was spamming, suchmoon made an overview of the number of posts per user. Such an overview could help here too, but it's a lot of work and I've seen users get away with
many deleted posts.
The yobit stats mostly helped yahoo to remove users from the campaign. I don't think mods looked into it. They get the post reports and delete those posts, so not sure what other case could be possibly built here.
