i think catsfive is right. Also, these tasks are automated and there is likely an AI bot involved so it doesn't matter how many devices you are using, they still have the info from the cell towers that triangulates your exact position within a couple of feet, so even that doesn't really save you. I'm no expert, I'm just putting together the pieces of what I think is true. If you know better, please share so that we can all be a bit safer.
