Can hoodlums master social network service? In Japanese hoodlums, it is possible. Japanese startup tasuke released social network service for hoodlums "Yanlove".
The main function of this is profile, diary, message and footprint(access history ). There is no difference between the function of this and other social network services. However, the design is unique. All of the site is the showy design which Japanese hoodlums likes. If users turn into a charged fee user, they can decorate to profile page.
And the most individual point is that the entry item of the profile has "a guidance career" and "an arrest career".
I think that this is effective in logging in to a police officer in secret :)
