Except the article talks about Indiana. It helps to read the article. You, did read the article, ... right?
This is what the whole "You've been served" process is about.
The general district court requires notification via posting on the front door of the last known address and delivery via standard 1st class mail. This can be and is easily abused by cherry picking the last known address used. The plaintiff just needs sign an affidavit that it was the last known address they were aware of. You could challenge that they didn't make a reasonable effort to get a good last known address, but the burden of proof is on you and you won't win.
Also if you rented a property and have vacated it, for example if your lease has ended, your landlord can post on the front door and mail notice to the vacated property and this is considered sufficient notice.
