Ancient maps show areas labeled as "Hic sunt leones", which translates to "Lions Live Here". Those labels were generally used for unknown or dangerous places called Terra Incognita, Undiscovered Country.
In times of satellites and space flights it seems more like a relic of ancient civilizations, but even today there are dangerous places full of predators. One of those is Internet. Internet, Modern Technology and Media are for many people Undiscovered Country and predators are hunting. Not looking for food anymore, but for money.
