This morning my daughter received a call.  When she answered she was quickly asked : “Are you there?” The obvious aim was to have her answer “Yes”.  If she had done so, instead of hanging up quickly, bad things might have started happening to her. These scammers want to record you saying “Yes” so they can charge you for all kinds of stuff, or do other bad things.

If you get such a call — HANGE UP IMMEDIATELY.
