Sex workers' ability to share information among themselves is essential for supporting all sex workers in negotiating their work, and in turning down work that is unsafe, underpaid, or undesirable. This is true of any job. But what does make this aspect of sex work unique, and what creates the thump of panic in my gut when I open such an e-mail, is that to share this lifeline of information could be construed as criminal. Selling sex in the United States is usually a misdemeanor, but sharing information with someone about how to do it is considered a more serious criminal offense.
