Hi – these postings are common in Craigslist. You can tell posts may be a scam by:

1) Pull up that page you linked to
2) Scroll to the bottom
3) Do CTRL-A (select All on Windows)

The ‘revealed’ text on that page begins with “double factories period stood radio carefully arrangement it triangle was laugh”. I think this text is meant to ibfuscate the posting – sort of like the garbage you get in some spams – so that the tools the website uses to find bogus posts get confused, and thus the post is not deleted.
