Wikileaks information was trustworthy and accurate. It may still be that the information prior to their canary expiring is okay, but anything released after can't be trusted.

I'd assume that once the canary died whichever actors compromised them scrubbed it.

It's been over a decade now, but I do have a machine somewhere with evidence.

Some nerd bigger than me here certainly has evidence available in a dropbox or somewhere accessible. I don't.
