Ghosting is abuse. It's a tactic by sexual predators. that's basically their endgame move. It's the dismissal part of what narcissists do to their targets after they are 'done' using them.

online socializing has encouraged a lot of narcissistic behavior.

It's just that it's so normalized and skated over we are not noticing it but it's bothering us for a reason. Cuz this shit would not have been tolerated prior internet days. There would be pitchforks at their door. A screaming person yelling to stop ignoring them and demanding proper closure like a person with some form of pride and manners does.

Heck even not responding to written letters was only done if you're dead.
