Just created a new self-hosted WordPress blog, and among the very first things, I "unchecked" the Allow link notifications from other blogs (pingbacks and trackbacks)
option under Settings > Discussion.
I was fixing a few things for the to-be-launched-soon blog, when I noticed a pingback on the default "Hello world!" post on my blog.
But I've already disabled pingbacks/trackbacks, so why exactly is this happening? What could be wrong?
