Age limits

Is it possible to make separate groups for just teens? It seems like it's becoming a bigger problem everyday.  There are people on here that actually need help with certain things an it's hard to take anything seriously with teens making a joke of it. I understand that there are some teens that are truly seeking advice but maybe they can have their own groups? Their own teen pregnancy, teen relationship, teen whatever. Butmaybe  to stop the rude comments and the immaturity there just needs to be an age restriction on the groups. Like all the adult groups should be 18+
