@Flakk - The totality of evidence has to point to the a consistent conclusion. Wayback Machine is only one source, other records are also a source. If the prosecution is only relying on Wayback they have a weak case. If Wayback tidies up all the loose ends then it makes the evidence more compelling. It appears the latter was done. Also, the prosecution provided witnesses to validate Wayback's methods that were cross-examined by the defense. So if there were serious holes, it should have come out with a competent defense.
