I donated and happy to support this service.
However, I had not paid attention to when saying ‘yes’ to gift aid, this signed me up permanently to something called swift aid, an intermediary service handling gift aid for charities. This may be a useful service for the charity, but I prefer not to be permanently signed up to any third party.
You can then unsubscribe from swift aid but they don’t make it easy. Plus, Just Giving automatically sets donations to add nearly 20% as a tip for the platform. I get that some money is required to run it but I wonder how much that tip generates in revenue for the platform?
Anyhow, just drawing attention to these two issues should anyone care.
