I especially don't think it's a bad thing because it's a hack that provides significant value to the donor. My wife and I made a small donation (we are fairly poor by US standards) a while back, and I teared up when they emailed me to tell me the girl was fully funded a few hours later. I probably would have gone back and donated to another case right then if they'd had any left (it was right after the Boston Marathon bombings, so I think they were seeing a spike in donors).
