Is this new? Build an archeology museum, and an archaeologist. You can basically dig up artifacts, sell them to the AI (without the museum being complete), and keep continually digging until all the AI civs run out of space (your Archaeologist doesn't disappear after three - only when the museum is full. So if it's never full because you keep selling artifacts...)
I mean it's thematic, and I'm not sure it's a major exploit - it requires a decent investment (late game), and is definitely not unlimited (there's not going to be that many empty AI archaeology museums). But I'm not sure it was intended for an unlimited archaeologist.
