If you see any advertisements about a “bodyguard” service, do not attempt to contact them. They are not a legitimate service. What they want is to kill/control the fools who fall for it. We do not know the reason as to why exactly, but there are theories.

If you hear buzzing, static, or humming sounds, please be very aware of your surroundings. This can be a strong indicator that you may see the advertisement soon. Especially if it’s night time, since all cases happen late at night.
