Well, I hope you don't get flamed as I really value your perspective and I want to think about this and try to get it right.
I'm not taking away her gaming forever btw! As I said up thread, I'm already considering ways she can do it safely, like getting her her own server (that we can monitor).
And, I haven't come down on her like a ton of bricks. Far from it, we had a lovely evening last night, we watched a TV show snuggled up together on the sofa, and I heard her do more piano playing last night than I have in weeks!
This morning she asked if she could have her phone back. I said no, because we have to have a good chat about trust before she can have it back, and some things will need to change. I said it's important we can trust her as the internet isn't a safe place, I love her and want to keep her safe. I said it nicely, not like she's in the dog house, and she seemed to accept it. She left for school in a good mood anyway.
Her old group of friends she played with online was mostly boys. I had no problem with that at all. Most of my friends were boys at that age, FWIW - simply because we had similar interests, nothing untoward. But they were the same age as me.
However, she's shown she's shown she just can't be trusted with Discord, so yes it's gone. She's been chatting to this 19 year old several times a day, every day, for the last 2 months. What 19 year old spends so much time talking, alone, to a 12 year old? (11 when they started talking, even).
She's so far from understanding why this is wrong I need to just put a stop to it. And while she doesn't understand and is prone to lying, well if it's not this guy, then it'll be another one, or another one - and eventually one who lives in the UK and has seriously bad intent. I'm not putting her at risk of that.
She's had loads of internet training btw. Ironically, she's the school's year 7 Online Safety Champion (a bit like a prefect role, but she's meant to promote online safety among her peers). She knows this stuff! Just doesn't think it applies to her, it transpires.
Good idea about using a unisex name, I'll add that to our chat, when we have it.
I'm determined to keep her offline for a while, so she can reconnect with real life a bit. I think her online gaming has got to the point it's become addictive, and the problem is bigger than just this 19 year old. There's a few things need recalibrating. Our trust, for one.
I will let her go back to gaming when I think she's ready, and any tips on that would be great.
But she's not going to be gaming and messaging with strangers, that's simply not going to happen anymore.
