this looked like something you would expect an alien civilisation to build
Wouldn't you have to have some previous data in order to expect what an alien civilization may or may not build?

Boyajian, who oversees the Planet Hunters project, recently published a paper looking at all the possible natural explanations for the objects and found all of them wanting except one – that another star had pulled a string of comets close to KIC 8462852. But even this would involve an incredibly improbable coincidence.
Well in something the size of the universe improbable coincidences will probably happen

Because we have some idea that most species wish to control their environment. It's more about detecting how much they've managed to control their environment and utilize mass amounts of energy that we're looking for. There are 4 types of civilizations that are out there.
Type 0: This is us. Pretty much only radio waves sent from these planets can be can be known, but they have to be close before they get so spread out that it's nothing but interstellar fuzz.
Type 1: Have mastered their planet entirely and can manipulate it. Buck Rodgers is an example of this.
Type 2: Have mastered their star and solar system and can manipulate it for its energy. This is what level they're talking about in the article. Star Trek would be an example of this type of civilization.
Type 3: Have mastered the Galaxy. Star Wars is an example of this.

Yes, but this star is only about 1500 light years distant. That is uncomfortably close to us for a Type II civilization.
