Also might be a way of finding out if your house is empty whilst your boat is not, worrying stuff.
On another forum, no, not that one, we had a rather annoying individual who seemed intent on creating trouble. One of the mods, navy trained, there's a clue, did some delving because the style of prose can be a pretty certain fingerprint, even for folk who use various forum names and different devices . It was who we thought it was but the mod concerned went further, much further by identifying the address, and even the room, picture from Google, from where the signal came from. The evidence went no further than to those of us involved with the forum management but it did shake the troll, as it was intended to. On an angling forum I was tracked by an individual, who even published a Google Earth location of my house, in an effort to find out where I go pike fishing, I did ask the police to have words and that, thankfully, was the end of it. Not a safe world.
