Unfortunately these things do happen and a lot more often, just that they haven't been caught.
On another note how social media is these days. People = being influencers , but only influencing ignorant masses. How a person would claim to said caught big fish weighing xx lbs. I know cuz when I've caught bigger fish and they don't weigh that much. Even some people who claim to cast xx lure weight xx distance on xx test # line. When said, I just lose all respect to give any credit to those type of people.
