Hi I need some help with perverts

Natalyn

The only boy in my class (small Christian school) is one of the biggest perverts there are. That goes to be a problem because he has eleven girls to mess with. All the crap he does, he does on snapchat instead of at school so the teachers never catch him. The girls in my class just ended up blocking him on the app. We kinda want to teach him a lesson but we don’t know how and were starting to fear he might do something to one of us or a little girl. Any advice as to how we should deal with him?
