I have friends who tell me they always donate because they are afraid of repercussions. Lately the calls are actually bots, and very good ones. I had a short conversation with one and I thought they were human, before I hung up. Next call sounded exactly like the first, so I asked "are you human?" and after asking 2-3 times I got transferred to a human and told them to take me off their list. Haven't been called since.
