Sure. That's why it's likely that - again, I don't know how this still bears repeating in this comment chain - IA still has the site archived, just not publicly accessible.
Because if it isn't publicly accessible it functionally doesn't exist, and what remains is a number of publications of questionable veracity.
Perhaps law enforcement will eventually be able to comb through the data, but there is no guarantee the general public ever will be able to.
It becomes a very questionable "trust us, they were bad" from sources that are demonstrably flawed.
(I am not saying they aren't bad, but from researching common claims like the owner is a pedophile and the Christchurch shooter posted on Kiwi Farms myself, it's clear that quite a few are exaggerated or not true.)
