I get these regularly, and for purchase notifications on sites where I expect the person will come back, I make an effort to track them down and notify them.
The only one where I actually put in quite a bit of effort was when I was getting the email notifications for downloading someone's CME (Continuing Medical Education) certificates as they completed courses. It turned out to be a real pain - I could find the person, but couldn't get hold of them. Approaching retirement age, rural, etc. - I think I finally ended up leaving voicemail on their son's # and with their church, though it probably would've been easier at that point to just sit down and actually write and mail a letter.
And the only one that really annoys me is the gun nut. I get more crap from whacked out black helicopter EEEEBOOOOOLLLAAAAA idiots now...... And he actually gave them money, so they just don't go away.
Have you tried emailing them and telling them that every time they contact you, you are going to donate some money to 1) Obama and 2) some organization that lobby for more gun control?
If I actually felt like engaging, I'd probably just buy the original donator a gift subscription to The Nation or something like that. I regard the actual organization as being much like Glen Beck - either a completely cynical huckster who doesn't actually believe any of the crap he spews, or someone so dissociated from reality that discussions are pointless. Either way, I'm not going to convince them of anything, and after an initial unsubscribe I just mark anything further as spam and be done with it.
