Every time someone subscribes and is potentially in one of the exception cases, have it add a record to a "people needing their possessives checked" database. Use a default of "s" or whatever's the most common in the meantime, then when you have a few moments to spare, view and tweak the ones which need tweaking.

($_='kkvvttuubbooppuuiiffssqqffssmmiibbddllffss')
