For clients, risks may include: fear of social stigma and family or work problems if their activities with prostitutes do not remain secret; health-related risks; being robbed; or, very rarely, being blackmailed or injured. German fashion designer Rudolph Moshammer, for example, was killed by a man who said that Moshammer had reneged on a promise to pay him for sex. If a male prostitute steals from a male client or accepts money without then "putting out" the agreed-upon sexual services, it is sometimes referred to as "rolling a john".
