I completely disagree. MM has set HERSELF up as an expert in online harm.
She may not have meant any harm 10 years ago as a minor actress, and may naively have believed including her friend, who runs the dubious club, to collate the names of 13 and 14 year olds, was a kindness. She would have no doubt been aware that they were vulnerable by the way they were posting details about their emotional state and showing her this in person too.
Basic safeguarding training tells you that you are not the friend of vulnerable young people who are strangers to you. You are not there to keep their secrets, join them in a secret club, write their name on some list compiled by some strange bloke, arrange meet ups with them, be their shoulder to cry on when you don't know them and have no expertise in their issues, be their object of worship and encourage them in this worship when they need proper, professional help. Granted, MM may not have known that at that time.
Her meeting the other night with these - still young, still vulnerable by the sounds of it - women is 10 years later, and in circumstances where she should know better. After she should have made herself aware of basic safeguarding issues, having held herself out to be an expert in this field on platform after platform. Meeting with women who may well still have the vulnerable mindsets planted in them as children by being online groupies is hugely irresponsible, given the position she has set herself up to occupy. Kids who are groomed in youth do not simply stop being vulnerable when they become young adults. I assume the Parent Network is all about teaching kids healthy use of the internet so they become healthy adult users of the internet. These young women appear to be neither. Meeting them - simply to feed MM's own massive ego and need to be fawned over - was a mistake. But luckily, she always has her apologists, and the press who just ignore it.
