Escort Sites
In practice, male escort sites can be divided into male escort directories and male escort agencies. Everything else is basically porn...
Male Escort Directories
An escort directory is a marketing platform. Anyone can sign up, that meets the basic criteria. In practice, the owners or managers of the directory have never met the individual who puts up the profile. They can neither answer a question, nor are they responsible for complaints.
Male Escort Agencies
An escort agency recruits suitable candidates. The candidates are properly vetted in an interview. All their personal information is kept on file.
As the agency knows every companion personally, they can answer questions about their companions. Needless to say, the agency is also happy to get feedback.
