I answered an ad on Craigsist for some freelance editing work. It was supposed to be a service that edits Asian "Engrish" into North American business English.
They sent me a fairly extensive edit test, which I took. Then the contact asked - via email - for my banking information for wire transfers. No secure server, no website, no documentation on the company.
When I said I wasn't comfortable emailing bank information, he said I could do it by phone.
I explained that I wouldn't give that information at all, because "for all I know, this could be an elaborate scam to obtain banking information". I said I could be paid by Paypal.
I have not heard back from them since, and the ad has been removed! I posted a warning on Craigslist.
The work sounded interesting. Too bad it was nonexistent!
I think I will pursue Woti's suggestion of looking for university and graduate students who need their papers and theses edited.
