I wouldn't donate anyway, if I didnt know them.
But I likely think just a scam.
I have one cousin who does this sort if stuff all the time. He went round pretending to be a firefighter, years ago, when they were all on strike so people would buy him free drinks.
He worked in a pub and collected money for a load of the regulars to go away, then did a bunk.
His daughter was ill when she was born did loads of fundraising for that. Family members assumed he had changed as the above events were 15 years before. Lots of family chipped in and helped. His wife was so grateful. There were clear in fundraising that some of the money was going to living costs as she couldnt work as his daughter needed a carer.
Anyway, his wife found out he had been sending dick pics to a much younger girl at work. And dipping into the funds to take a third woman away. She moved the money and left him. I am confident the money has now been spent on the adaptations the young girl required. The mum is back at work.
Since then his new girlfriend seems to have taken up crowd funding for various people. I suspect he is up to old tricks but just giving just say they cant find the fundraising is connected to him at all. And he has never been convicted of anything so dont do anything.
Its appalling. You have no clue who you are giving to or what they will spend it on. So, personally, I would stay clear.
