RFTools Shape Cards, a while ago, have been blacklisted due to some players exploiting Grief Prevention with them. The only item that would allow to exploit the plugin is the RFTools Builder. Since the Shape Cards provide utility for many other machines, such as the Shield Projector, is it not better to blacklist the RFTools Builder rather than the Shape Cards? Additionally, as far as I know, only Quarry Shape Cards allow the Builder to mine existing blocks in the world.
Hello there. The builder was left unbanned due to it having multiple uses. The shape cards were causing the builder to ignore protection so we had to ban them. Hope this clears it up for you.
