To think this mum should have been more concerned

[consideratealpaca]

Dd9 has an account on a popular online gaming platform. During lockdown she spent a reasonable amount of time playing this game with her class friends from school. One particular girl and DD have butted heads a few times and fell out, which to me seemed like normal kid like behaviour and I wasn't concerned.
Despite me trying to persuade DD not to, she opted to spend some of her birthday money on 'diamonds' to enhance her game experience. I think she spent roughly £100 in dribs and drabs, which I wasn't impressed about, but it is her money when all is said and done.
Last week she came to me and said her account had been 'hacked' and all her diamonds, special objects etc had been stolen. She was then shut out of her own account. It finally transpired that she'd given the girl in her class who she frequently argues with her log in details.
Ordinarily I wouldn't particularly care but this child has stolen the things she bought with her birthday money as well as all the credits she had accrued in game play.
The girls had a brief exchange on WhatsApp and the class friend admitted she had taken my daughters diamonds etc and then changed her password.
I'm pretty sure I can take back control of the account for her, but everything is now lost. Her friend meanwhile, has all of my daughters diamonds and credits.

I messaged the mother of the child in question and whilst the message was read, it was ignored. So I approached her in a polite and friendly way in the playground this afternoon. I was hoping that she'd be shocked at her daughter's behaviour and perhaps we'd get an apology at least. I do not want to be reimbursed for the lost money, and stated that from the start.
The mother's reaction was just to shrug and waffle about not getting involved. Am I right to be mildly pissed off, or ridiculous for making an issue of it to begin with?

Well done! Doesn’t it feel better when you don’t stoop to their level.

OP, speaking from bitter experience, my only additional comment (because I think you've done brilliantly here) is don't hide it. I mean, you don't need to put it on the school facebook group, but feel free to answer questions. I had a parent have a complete go at me. I was dignified but firm etc etc. But.... somehow everyone was so embarassed/heard her side that I was promptly sidelined. Years later, when people actually asked me they were all shocked by what had happened (while simultanesouly NOT being shocked as by now they all knew this woman better!).

Oh my she is vile.

OP, in my day we played with our fingers. Middle finger up, the rest down .

I also wouldn’t keep quiet. This woman/girl will have precious form!

If I had overheard that I would have given you a high five

Outrageous. My DS is 10 and plays Roblox too but never, ever is real life money spent on Robux or similar. It's just a hard no and he accepts that because, well, he is 10, trusts my opinion, understands my POV and my responsibility to make the final decisions. The other parent is being shit but she presumably hasn't got £100 lying around!!!

Tbh it’s a life lesson for your daughter (and you in terms of allowing them to spend so much on virtual stuff!)
. My son spent £5 on robux and someone convinced him to swap something then didn’t fulfil the swap and he lost something or other. He was v v sad, but we used it as an opportunity to talk about trusting ppl online.

But yes the other mum could’ve been embarrassed or apologetic at her daughters behaviour.

I read on further into this thread. Glad it’s sorted. She sounds abominable. As it involved real life ppl you could try to resolve it, whereas my sons situ was someone he didn’t know online, so it makes sense that you did

Well I hope that's the end of it @consideratealpaca and the raging cow doesn't continue any further. It's just the kids you need to be wary about now. You don't know what this nasty mum is encouraging her daughter to do.
