Go fund me could add their fee to the amount set that's easily done.They won’t do that cause they take around 15% of funds raised, that’s how places like GFM and Just Giving make their coin.
The person who set up the fund should have been a bit smarter about it and put the money into some sort of trust for him rather than just gifting him the money.
GFM should be explaining things like trusts and ways to give money to people so they don’t piss it up the wall.
I think from a government petition side of things it’d struggle to meet their criteria as there’s a limit to how much of a description you can put in and it can’t be specifically targeting an individual.
There are other petition sites I think would host it though?
