[Malaysia] Grandmother trapped in romance scam, should I just give up?
TLDR: Grandmother involved in romance scam with "Elon Musk", is the only person who has agreed to pay for me and my siblings' education. I'm wondering if there's anything I can do, or if I should just move on with life and let her be, leaving her savings up to fate.
For context:
My grandmother (76 this year) has been trapped in a romance scam for at least half a year now. She's been a widowed woman for the majority of her life, and her personality (suspected personality disorder) makes it insanely difficult for anyone to bear talking to her. As a result, she's been very lonely for the majority of her life, aside from the companionship of her own family and maybe a few friends here and there who can still manage to deal with her antics. She also lives alone, with my little brother going over to her place every weekend or so.
Not too long ago, she started chatting with a certain "Elon Musk" (I'll be calling him EM for short) on Facebook, which was of course, not the real Elon Musk. From there on, she gave her phone number to EM and they started talking daily. It wasn't until she started talking about how she had "won a prize through Elon Musk's game" and had $250K USD pending that we were aware of the scam. On top of that, it seemed like EM was lovebombing her, talking about how they were going to get engaged, and that how she was EM's "one and only".
Of course, my brothers and I tried to stop her and talk some sense into her but she listened to none of it, and somehow fell even deeper into the scam. It boiled to a point where my mother had to physically drag her over to the police station, where she then proceeded to scream at the chief inspector for half an hour before walking out silently, pretending as if she understood that she had been scammed. Naturally, this wasn't the case as she went back to her shenanigans of sending over money through gift cards not even a week later.
After this point, my mother and all of her children (most of which whom never had a good relation with her to begin with) essentially gave up on her. My mother would only watch her very vaguely to make sure that she wasn't doing anything too egregious.
The main problem in all of this is that ever since me and my siblings were little, my grandmother would always emphasize on the importance of education and how she would gladly support us during our tertiary education (in which she did in fact have a savings account for). My parents were never really wealthy, with my mother being a housewife primarily and my father having failed to run a business. They had gotten divorced a while back, so that exacerbated the whole financial situation even more. From what I could tell, they had never actually planned for our tertiary education. That's why my grandmother played such an important role in our lives, aside from being my primary caregiver for the earlier years of my life, she was also essentially the only "backup plan" incase none of us were able to get through college by our own means.
However ever since she was involved in this scam, it was like she had completely forgone all common sense, having sent upwards of RM20K to EM, possibly more as of present (I'm not sure, I don't have access to her financials). This would completely drain her of her monthly pension (she's a retired lecturer, which makes all of this even worse), and tap into her other savings.
As of right now, I don't know how much money she has left, let alone if there is anything I can even do for her. I'm currently studying in a college across the country, where my tuition fees are being funded by an external scholarship which I am extremely lucky to have gotten. I fear that there isn't much I can do to stop her online activities, since I don't even have physical access to any of her devices. Both of my younger siblings are still in school, and I would really not like to disrupt their studies because of this matter.
Anyway, I'm not sure if there's any way out of this anymore. None of my siblings can do anything, as every time they try to block one account on her phone, at least 3 different ones pop up like a hydra's head, requesting for more money and asking what had happened. From what I know, she's also slowly falling for a different guy, slowly being "disillusioned" with EM. Of course, they're all scam accounts, so it doesn't really matter in the grand scheme of things.
Even if there isn't anything I can do, at the very least let this serve as a cautionary tale on how lonely elders are extremely vulnerable. If any of you have older parents or grandparents that live mostly solitarily, please help to get them involved in a community, as it could be the very thing preventing them from being drained of all of their life savings.
