That's a pretty weak set of evidence you have there for a claim as big as 'Snopes is ONE OF THE LEAST credible sources that you can find', emphasis mine.
I am not aware of any other site that is both excluded by the internet archive and has been found in the past to engage in dishonest attempts of covering up its mistakes. I would argue that both of them combined is quite a strong of an evidence for my claim.
