One horror story could be when the hookup arranged through PGP (Pretty Good Privacy, though it's misused here for inappropriate meet - ups) turned out to be someone completely different from what was described.

This completely violated the trust that was supposed to be there in a hookup situation. It made the other person feel really exposed and betrayed.
