I think I'm done donating for a while really. The sheer quantity of spam I get on my phone and email from random, semi-related causes and politicians all around the country is so irritating.
I would love to give more but I simply cannot abide any organization that has zero respect for privacy as politicians do. I've given to a handful of charities but only when they have a clear privacy policy that is explicit about not sharing or selling information and has explicit opt-in for marketing materials
I actually don't get hassled much by charities aside from some occasional junk mail, which I think is fine. They don't seem to pass my info around as aggressively as political causes.
