Cops, Kardashians Alarmed ... Kylie Needs to Cool It With Social Media

Police are warning Kylie Jenner to pull the reins in when it comes to posting pics on social media, because stalkers and others up to no good are using it as a road map to her doorstep.

Cops are especially concerned because one obsessed fan has tried to make his way into her home at least 10 times. He's under a psych hold now, but he'll be released soon, and police want Kylie to immediately get a restraining order.

But they're even more concerned that her social media posts show she's rich with expensive jewelry, fancy cars and other trappings of wealth. It's an invitation for burglars and home invasion robbers to make their way to her home.

What's more ... we're told Kris and other members of her family are on board, and very concerned Kylie is overdoing it and giving too much information about her surroundings away on social media.

What we don't know ... if Kylie will put her safety above social media.
