You're not the only one who is annoyed. My father died YEARS ago, but I still get lots and lots mail for him from the ACLU, with membership cards and "suggested donation" and the like.

The mailings that really annoy me are the "FINAL membership notice". I've gotten at least 3 of those. Maybe they don't know what "final" means? But it's annoyed me enough that I will not donate to them. Not to mention how much money they have wasted in these, oh, once-a-month mailings over the last few years...
