So in a block earlier today I encountered a spam bot (surprise) but what was surprising is I was having a really hard time finding him. Eventually i found him. He was behind the lodging building. You can squeeze in-between the buildings and get behind. I don't think SEGA intended for this. As it is tricky to get out of the back once you've squeezed in. The game doesn't want you leaving that behind the building area once you are there. Seems getting back there so easily is a glitch to begin with.
But thankfully you don't need to go back there in order to report the bot. just getting up close to the front of the building is close enough to get the bot to show up in nearby players.
I'm including some screenshots in case my description doesn't make much sense. So others can report bots that are hiding out in this location.
