Police received 110 reports related to so-called "revenge porn" — posting sexually explicit images of former lovers online — in the first month since a law prohibiting the act took effect in late November, a survey showed Thursday.

Conducted by police between Nov. 27 and Dec. 31 last year, the survey showed that the victims in 65 cases were in their 20s or younger, and that the largest group of perpetrators were those in their 30s. The victims in 99 of the cases were female.

The police have dealt with the crimes by requesting Internet service providers to delete sexual images that were posted without the subject's consent, warning offenders engaged in revenge porn and advising victims on ways to limit the damage.
