If it is, the next step might be disabling signature campaigns which pay their participants in altcoins or tokens (not Bitcoin). After all, the last step might be disabling all signature campaign, but I guess we might not see such action in coming months. I saw post quality changed positively, and forum users tend to be more constructive. For spammers, they already get perma-bans or nukes, and will be get such punishments more.
I am still waiting for activation of reporter badges, that are another motivation to eliminate bad posters.
