I don't think it's wise for a13 year old to use social media in this manner. She could have stated that she was 13. She was also replying to posts at 11.31 PM... Personally I think a 13 year should be asleep or at the very least not be on a computer.. What would have happened if someone had posted " I have your phone please meet me to collect it" The parents should take responsibility and apologise to other forum users for allowing their 13 year old to use the forum in this manner.
