New postings on TSTOtips is not from the authors who the site says posted them!

I don't like to offer any tips on how to deceive people, but, the longer this goes on, the more obvious it becomes that all the posts and comments related to the discount site are being written by the same person. If you ignore the dates and "usernames" and just consider the sentence structure, phrasing, and vocabulary, it all looks like one big sales pitch from the same person.
