my junk mail
has shown me that one of the charities that I regularly donate to has sold or given away my address to other charities.
A) I hate junk mail from charities–please spend your money on what I’m donating my money to get you to do, not on sending junk mail and B) I’m giving you my money because I trust what you do with it. Selling my address isn’t a great way to retain my trust.
