Just curious why you used an address that's associated with you. Choosing the address of a place like a park, which is a real address that has no mailbox or direct association with you, ought to be the default if you don't want to be spammed to hell and back.
I was young and naive!
Also, I wanted to make the donation immediately, while I was thinking about it. I didn’t want to put it on a back shelf of my mind and forget about it for a few years, and I assumed “The Good Guys” wouldn’t use my information in a negative way.
