Is Inno filling the player field with bots accounts?

Probably just a tinfoil hat moment but I'm curious of what everyone's thinking.

I've befriended a player not long ago on all 3 worlds I'm playing and I noticed their city is exactly the same on all worlds.

Tried to ask directly with a PM but they left the conversation without responding, but I can see them sort of interacting (trades and donations to GB).
