In my free time, I help maintain the web presence for a small non-profit org with memberships. The original system when I started helping was a bespoke system that was smart in many ways (essentially a static site generator with membership control years before SSGs were cool, with regular automated tests), but the guy who wrote it absolutely insisted on storing passwords in plaintext and could not be convinced otherwise. Eventually he had to drop the volunteer position due to other things in life, and the first thing we did was correct this issue.
