This is a legitimate claim. You might wanna take a look at this[0]. I've blocked out the project title and the buyer's name, becasue i don't want my real name associate with my HN handle.

Dark Red: Buyer's Name

Turquoise: Project Title

P.S.

Not sure how you got the "unpaid advertisement" idea from my original comment. That is a complete opposite of an advertisement. However, it advertises the fact that you can get work done for free. Maybe that's what you are trying to say :)
