Because there are so many newly registered freelancers who have no experience and are completely unprepared to recognize and avoid the scams. UW is not a controlled environment. They let most anybody in who can fog a mirror, on both the client and the freelancer sides. Scammers abound here, just like they do outside the platform. It's a grand mishmash of the lazy, the clueless, the expert, the professional, the crooked, the straight, the dabbler, the full-timer supporting a family, the less experienced, the greybeards. Clowns to the left of you, jokers to the right.
Learn the ToS, so you'll know what is and is not permitted. If you haven't freelanced before, read all you can about it, there's much to know that is independent of UW. Get familiar with the information offered in the Help and Support section and the helpful articles pinned to the tops of these discussion boards. Browse the discussions and learn from others' mistakes and experiences. And always, be prepared and inclined to learn from your own mistakes because you will make some. We all do. The goal is not to make the same mistake twice.
