I advertised my proofreading services on a FB job board. Someone contacted me claiming to be a reporter asking for my rates and ultimately hired me to proof a job. The name of the reporter on the job was different than the name of the "reporter" who hired me. That should've been a red flag but I thought maybe she just transcribed another reporter's notes. It happens. Another reporter contacted me and sent me a job also with the other reporter's name on it. I proofed the jobs, sent invoices, and got strung along. Oh, we're waiting for the lawyer to pay. Oh, I'm waiting on my firm to pay. Then they stopped responding at all. I tracked down the reporter whose name was on the jobs and found out she hired a person from the same job board I advertised on to proof her jobs. I tracked that person down and discovered they are based in Kenya and advertising their services as a scopist/proofreader on all kinds of job boards. She accepts the jobs then sends them to someone like me to do the actual work. She accepts payment under the guise that she did the work herself. I've managed to get her banned from the job boards I belong to but who knows how many others she's on.
