Ms Lauren Reynolds:

As Ms Muireann Whelan said, yesterday in our workshops for first and second years we very much stressed what we consider to be the "granny rule", which would involve them considering whether they would want their grandmothers or even parents to see what they are posting or the pictures they are sending. If they would be mortified, there is probably a reason and this should indicate to them that they probably should not be posting or sending the picture in the first place. Perhaps knowing what one's parents would think if they saw the picture would draw attention to the fact that it might not be so appropriate.
