How do you deal with spam on whatsapp?

Question

Fight against spam

Hello! I created a group in vatsap, invited people from the phone book, more people pulled up. The group assumes a discussion of a certain topic. Spam began to appear - some numbers are added and porn is posted. I have the only action with a long tap on their message "delete from me". - that is, I delete it from myself, and everyone else sees porn spam? Somehow not very ... how to delete a spam message completely? How do you even prevent this? In viber, the group is 5 times larger in size and there is no such thing.
