Thanks for reminding me about this. One thing I've established with my siblings was that none of us should transfer any money via a service like Paypal, Venmo, etc to each other without an explicit casual phone call first. It can't just be a text or a phone call asking for money, you have to have a casual conversation first. How is work? How's blah blah, what are you getting for dinner tonight, etc. For the case of elderly parents, I'm lucky that they would immediately hand that off as busy-work to siblings. Like they would never go to Western Union, they would call a child and say hey your sibling requested such and such can you go do that which would then raise all of the alarms.
