Ten years ago when location publishing was novel, there were worries that it'd make it easy to burgle people, since you'd know when they weren't home. I haven't heard of any burglaries specifically attributable to someone posting their location online, but it's what I think about every time I see someone do this.
It seems like he wasn't robbed because he posted his location, but because he posted his location as well as ludicrous amounts of cash, jewelry, and vehicles.
I'm sure it happens all the time. I even learned recently while bingewatching that social media is how the Bling Ring burglary teens would figure out when Paris Hilton, etc weren't home.
Also, social media location services have been used to figure out where people were in order to follow them and murder them e.g. Molly McLaren. (Social Media Murders Episode 3, I said I was bingewatching...)
For this reason (logical or not) I always feel avoid posting pictures of myself while on vacation and have a tendency to post a "summary" after I return home.
