I think the blacklist is the simple and most direct way to attack the abuse.
I also really appreciate the tiered whitelist you've created for your service.
I think smartsteem is helping set the bar for the way these services should operate.
I proudly use smartsteem for Hots or Shots and will continue to do so until I've built up a large enough audience that will allow me to just operate the show organically.
Thanks for all that you do @therealwolf
