My 17 yr old daughter has split from her boyfriend, he has posted something vile and offensive about her on twitter which has been 'retweeted' or 'favourited' by 24 others. My daughter is upset obviously but feels humiliated more than anything else that the tweet remains despite her asking him to remove it. Not sure what to do, some saying leave alone because any retaliation will make it worse but I'm so enraged on her behalf. Being a complete luddite I don't know what constitutes an illegal tweet - presumably racist tweets which this isn't - or can people tweet whatever they like?Should I contact his school? I do realise that part of doing that would be me wanting revenge ( he's an all A grade A level student and a sports star - their ideal pupil ) and I am just not that sort of person but he is really trying my patience. Advice please, thank you
