I guess you could say that pedos and other predators have a ‘something is amiss’ vibe, as I’ve picked them out before knowing a person long.
You mean you’ve picked out the ones that you know got caught or exposed.
There is no such thing as a “vibe” for predators or pedophiles just like there’s no such thing as a “vibe” for a murderer. Sorry, you don’t have psychic powers.
