Such sites can face legal difficulties; in 2015, Rentboy.com – a well-known American site – was shut down by the United States Department of Homeland Security and its operators charged with facilitating prostitution and other charges. Recent research suggests a substantial growth in numbers of online escorts worldwide, to the extent that the online market accounts for the vast majority of male sex workers. Major cities in Europe and the Eastern Hemisphere often have one or more areas where male street prostitutes regularly make themselves available to potential clients who drive by in cars. Such an area may have a locally-known informal name. These areas tend to be risky for both the client and the prostitute, from a legal perspective when it is in a region where street prostitution or solicitation is prohibited by law, or also from a safety perspective. These areas may be targets for surveillance and arrests by law enforcement. Some male prostitutes solicit potential clients in other public spaces such as bus terminals, parks and rest stops. Male prostitutes may attempt to work in gay bathhouses, adult bookstores or sex clubs, but prostitution is usually prohibited in such establishments, and known prostitutes are often banned by management. However, in some places it is overlooked in order to keep the flow of business. A male prostitute may work in a male brothel, also known in some places as a "stable". The Cleveland Street scandal featured a London male brothel frequented by aristocrats, in 1889, when male homosexuality was illegal in the United Kingdom. In her biography "The First Lady", April Ashley quotes her ex-husband, the late Hon. Arthur Corbett, who worked in the City of London, and was addicted to cross-dressing, as telling her in 1960: "There's a male brothel, I pay the boys to dress me up, then masturbate me." In order to work in a legal brothel in Nevada, a cervical exam is required by law, implying that men could not work as prostitutes. In November 2005, Heidi Fleiss said that she would partner with brothel owner Joe Richards to turn Richards' legal Cherry Patch Ranch brothel in Crystal, Nevada into an establishment that would employ male prostitutes and cater exclusively to female customers, a first in Nevada. However, in 2009, Fleiss said that she had abandoned her plans to open such a brothel. In late 2009, the owner of the Shady Lady Ranch brothel challenged this provision before the Nye County Licensing and Liquor Board and prevailed. In January 2010, the brothel hired a male prostitute who offered his services to female clients, but he left the ranch a few weeks later.
