Following the lead of Caleb on Christianity.SE, who requested that the tags "christianity" and "christian" be blacklisted six days into the private beta, I recommend that the tag blender be blacklisted. As we are on a site about Blender, having such a tag adds no value to any question because any on-topic question will be about Blender.
There should already be a
^blender$ intrinsic tag blacklist. All sites (betas, at any rate) have this.
