I suppose the privacy zones are always a light weight measure in some cases
If you have a ride that starts in one direction and comes back from the exact opposite then it is obvious that you must live in the middle bit
which in some cases narrows it down to one or two houses
In my case it could be anywhere at this end of the road - or the next road along.
The bloke next door did have his mountain bikes nicked some years before I moved in - he reckons someone saw his bikes on his car roof and followed him home then broke in at night
But I have certainly heard accounts of it happening after logged rides - and Strava is the obvious place to look for possible victims I suppose
I have also seen people putting screen shots of their ride on sites like this - and more public places such as Reddit and Quora - and as the screen shot comes from their account the whole ride is shown including the exact start and finish
so just add the mention of their carbon fibre bike with helium filled tyres and plutonium plated seat post (I may have made some of that up!!) and you have a clear target
