In New Zealand, the Hell's Angels club in Whanganui has been set down as a pokestop. That's probably not the best place to wander into with your smartphone to catch some Pokémons.
Over in the American state of Missouri, the police in the city of O'Fallon, on the outskirts of St Louis, is warning Pokémon hunters that armed thugs have been luring players with bait and robbed them. The robbers have been arrested.
The game itself is being subverted too. Players are being asked to "sideload" Pokémon Go for Android by game tutorials on the internet which means installing it from unknown sources rather than the official Google Play app store that vets what's published to keep users safe.
Sideloading bogus Pokémon Go apps is a really bad idea: you're likely to have your device infected by a nasty remote access tool, or RAT, that nasty people have attached to the game.
The lesson for developers of anything is of course that there really is a law of unintended consequences.
A RAT gives attackers full control over your device, and that means everything: the phone, the camera on it, the microphone and more. Doing this could not only allow criminals spy on you remotely, but to run up huge bills by abusing your phone's connections. Don't do it.
Nothing of the above will stop the success of the game of course. Things could possibly go more wrong, and I hope they won't and that everyone playing Pokémon Go will be safe, along with their devices.
The lesson for developers of anything is of course that there really is a law of unintended consequences. If you're successful and your game or other app becomes a super mega hyper hit like Pokémon Go, it will attract bad people who make it their business to hurt others.
Millions of Pokémon Go players represents not just a massive opportunity, but a huge responsibility as well. That's a situation which is nothing new as such, but the internet with its immediate access to enormous global audience that connect to each other globally and locally makes it challenging, to say the least, to deal with.
When you meld the virtual domain with real world, think about what actually happens in the latter. Before something terrible happens, ideally.
