1) Deception 1:
If this were true, the "deception" would be a legal necessity for operation in many locations.
2) Deception 2:
This is generally true, though there are of course registered companies that are generally more trustworthy if only because their operations can be examined and interrupted by legal issues if fraud occurs.
Also, though, writers will tend to put their efforts where the pay is better. Company work might not be lower quality, but better writers will tend to work directly with customers as much as they can, leaving others to do a great deal of the company work. The situation is more complex than presented in the dichotomy you describe.
3 Deception 3:
Very true. Again, the situation is more complex when it comes to the link between competence and English-language status; there are highly comptent ESL writers that nonetheless make grammar and usage mistakes that would not be expected of a native speaker, and native speaking writers that will use language unexpected for an ESL student. Students need competence first and foremost, but competence includes language mechanics.
4)Deception 4:
Unequivocally true. The only country that matters, after a writer's competence and appropriateness has been established, is the country to which a payment is sent. If making a payment means the money is completely irretrievable, think twice.
5)Deception 5:
I don't think anyone ever credited WritersBeware as the sole reason any scams were exposed. It also seems as though most of the scams exposed here, by WritersBEware and others, are still in operation. I don't know that an industry such as this, which operates in a very grey area of the law and has a constant source of new and inexperienced customers, truly
can be cleaned up, but WritersBeware was certainly effective at responding to requests for information about various companies and often substantiating those responses with off-site evidence. It seems like using a spoon to keep back the ocean, but it was something.
