How can I minimise the spread of images?

Unfortunately, once shared online, many images end up on sites that are used for adult gratification. Act fast to help prevent this. If schoolmates are involved, the school may be able to help. You can:

help your child to identify where the images might be and send take-down requests to all sites
send messages to all children who may have received an image and ask them to delete it immediately
help to block people who make offensive comments about your child and report them to the police if necessary.
