Unfortunately the campaign was unsuccessful and octopus paxarboli went extinct not long after the page first was published, before internet access was common and before smartphones could easily take pictures of it etc. Just because there's minimal evidence of something from before the internet, on the internet, doesn't make it a hoax.

Largely, the campaign failed because of the joint US/Canadian invasion of the Republic of Cascadia based on (ironically, false) claims of Weapons of Media Deception (WMD) being deployed with imminent plans for use against North American civilian targets.
