560 AD in my current game and already 3 have popped in my capital, I settled 2 and built the yard with the third, sure infiltration is a great way to gain insta -overpowered espionage on 1 person for a long time, but if they are on my continent, they are just millitary fodder anyways.
The surprising thing is that I gain all the bennefits, of the infilitration this way, yet they will never go away, so if you get multiples, settling +beauracracy +yard will get you a long way.
Edit its around 1000 AD now and 4 popped, If you get multiples this is definately a good use, 3 stolen techs, and in general i'm wreaking havoc with spies whenever I want, while still maintaining a massive economy 0 percent espionage and over 140 per turn.
