I found out that the author of a blog post paid a maid to clean their house, and sends their laundry out. Therefore, the blog post was written by the maid, or one of the laundromat employees. So I closed it.

That's a false equivalence. You might read a blog post about engineering from someone who paid a maid to clean their house, and sends their laundry out.

But would you read their blog post on laundry tips?

No - it's just as easy for you to send out your own laundry.

Err, no, the equivalent would be if the author had written an article about laundry, and how important it is to pay attention to all the details... then you realize the photo of his laundry still has a tag on it from the laundromat.
