A couple of years ago, I gave $50 to an issue-oriented charitable cause. It was a one-off donation, given as a show of support when their issue was front-and-center. I had no intention of becoming a regular supporter.
I should have donated anonymously.
Ever since, I receive 2-4 mailings per month, from this and related organizations, soliciting additional donations. Donations which most definitely will not be forthcoming. If we value the cost per mailing at $0.50, easily half of the value of my donation has been consumed, thus far, in soliciting further support.
It's sickening. Besides the junk-mail nuisance and natural resource waste, the sheer inefficiency of the process is appalling. I'm not singling out this organization, I'm pretty sure this is the dark nature of the organizing/fundraising process. Years ago, I read snarky advice, somewhat but not entirely tongue-in-cheek, that if you wanted to inflict harm on a cause you dislike, the thing to do would be to give them a small amount of money. $15, say. Then sit back and watch as they spend several times that amount in the following years, in the hopeless effort to inveigle further contributions.
I wish I had remembered that bit of wisdom.
