Matchdoctor, MyFreePersonals, MegaFriends and DateHookup allow people to post, view and respond to personal adult ads. Posting free ads on these sites requires registering for free memberships. Alternatively, Craigslist allows people to post free personal ads without requiring memberships, but users must select a geographical location to view the site.
Personal ad sites generally caution users to beware of scams and to not give money or personal information out too soon. Matchdoctor and Craigslist both provide full-page personal safety tips that include how to plan safe first-time meetings in public venues, ensure that friends or family members are aware of the meetings, and report online harassment and abuse to site owners.
