“Much of the evidence we cite is from charities’ own webpages. Charities have the ability to change their webpages to potentially alter, conceal, and/or destroy evidence that we have cited”
https://web.archive.org/ (aka Wayback Machine) regularly saves old versions of webpages. Maybe select a bunch of charities at random to see how thorough it is?
