Still not a copyright violation. You can't copyright a fact. I write a post that says "I am renting an apartment at 221B Baker Street." Padmapper copies it.

Still not a copyright violation. You can't copyright a fact. I write a post that says "I am renting an apartment at 221B Baker Street." Padmapper copies it. My post is not copyrightable, so (regardless of what you think of the copyrightability of a collection of facts), Padmapper has not violated the copyright on my single post because it doesn't exist. If I were to include some original creative text that was copyrightable, Padmapper is still fine, because they only copy the facts of the post not the full text.
