The mysterious whale stealing fish off of fishing lines, ID'd even though it only shows it's lower jaw.
How interesting that you mention whales. There are far more interesting real mysteries in that realm.
Take the Blue Whale. We have no idea what it's migration routes might be, nor where it mates, nor why it is that their whales songs stop sometimes and simultaneously resume with a new song months later which it seems impossible that all Blue whales learned simultaneously at the latest meeting of the "Itty Bitty Whale Song Committee" or something. Nobody knows for sure.
Now, despite all of these genuine mysteries about the largest creature which has ever been actually found on this planet, which can trivially been shown to exist for centuries (whalers caught them), Footers spend time looking for a delusional phantom which cannot be shown to exist, leaves no traces, leaves no evidence, leaves no photos, leaves no trace at all, no more than unicorns, or pixies, or ghosts.
Take the giant squid. It is known to exist because corpses wash up from time particularly in New Zealand. Nobody knows why new Zealand. Until a couple of years ago, there was not any record of a live giant squid. Nevertheless, they were demonstrably real due to corpses, the fact that they are they prime component of sperm whale diets (which we also know are real), ambergris, and sperm whale scarring. Speaking of sperm whales, we have no idea how they avoid the bends when they undertake their deep sea diving hunts for those giant squid.
Now it seems to me that as an actual denizen of this world, real mysteries would be far more deserving of attention rather than myths and nonsense. And the corollary is that footers must perforce have a different interest than research into a real mystery, preferring as they do, no research into a fake mystery. What might that interest be?
Given that it demonstrably is not to find an actual animal, to provide hoaxes and to actively avoid providing any evidence, there are few remaining options.
Personally, I mostly lurk BF threads and post little, but I find the entire thing risible. Chris, for example, claims for years that he has hard evidence which he cannot show for reasons he cannot bring himself to rationally explain. Why is that? It's **** all use if you never show it to anyone. Bigfoot family group from 15 feet? Well that has got to be high resolution, right? Wrong. Nobody has ever seen it. And so forth.
