If she wants to help, persuade them to go to a debt management charity and take charge of their own finances.
If they are genuine, this will help far more than helping them get more money (& defaulting). If they are not, well, you can be glad that you didn't walk into a situation where virtual strangers can take £6000 of your hard earning money.
I used CAP when i realised i couldnt work myself out of debt (h left me with his huge loans and a new born baby, when i became disabled and couldnt support him any longer. He also left me injured. He was a lovely man).
Anyway, they helped with everything from working out a budget and how much I could pay back in reality, and dealing with the bank and getting them to accept a revised agreement and cut interest rates. They even brought me food, although i wasnt in wuite that much trouble, i can imagine bloodbath would have helped in the gap between the first meeting and them drawing up a new agreement.
They wanted me to go bankrupt but I felt v strongly I wanted to pay it - though in retrospect I wish I hadn't as I beggared myself and still have a screwed credit rating.
Anyway, my point is, that helped sooooo much more than friends bailing me out, although one family friend helped alot, she made it clear she wouldn't accept the money back, as she didn't believe in lending money to friends. But I had £25k in unsecured loans and credit cards (thanks so much h), so even £6k would have kept me going for another couple of months before I ended up in exactly the same situation.
CAP said that was typical, and how people get into these situations, they can never get enough money to do anything but continue living in debt and slide further down that hole.
So even 'helping' probably won't actually help them, just prolong the problem...
