Evil generally is deceptive and seductive often attractive....a counterfeit of what is real and or an impostor. Many times offering just enough truth to lure one in as in a trap.
These stories, as this one, have been written for years and always draw attention to those who are looking for supernatural encounters.
Evil exists, yes, but it generally doesn't reveal itself as something evil. That's why people get suckered into to the sensual and feely type of encounters. It plays on their desires to see the unseen world they imagine it to be.
Unfortunately, Satan doesn’t play by man-made rules. The Bible warns us that demonic activity will increase before Christ returns. So while I generally agree with you that one must invite Satan in through word or deed, I reject the idea that Satan is typically seductive rather than aggressive. A lion seeking to devour is not seductive.
