Here's the thread from when this was originally brought to 'everyone's' attention.

Notice that no one mentioned of any possible scoring made from this. I added these 275 workers at 1996 A.D. I think. So with 275 specialists at 1 pt *2 (warlord level), that was 550 pts. Now, I had about 10% of the game left (54 turns out of 540), so this only helped my score by 55 pts (less when you consider starvation). In my current game with this 'worker farming' or 'specialists relocation', whatever you want to call it, this has helped my score in the thousands!
Normally, when people have excess workers after all the terrain is improved they added them into any city that still was growing, thus speeding up the time it would take that city to reach max population and help their score by 1 or 2 points maybe. And there have been some times where every city already was maxed out, thus if you add 1 worker to each city, they all starve on the next turn anyways, so you might as well have disbanded them.
I don't support the idea of the starvation (if you have a city size 12 and now it only has enough food to feed 8, you lose 4 pop points in that one turn). This would lead to another exploit. Since citizens can't work on a tile that an enemy is fortified on, players would send tons of units all over the place and fortify on every tile, thus starving a city from size 12 to 1 in just 1 turn!
I don't like the idea of not allowing the addition of settlers/workers into cities over size 12, either. Remember, in an ideal city, the city has 20 tiles to work. Should the limit be 20, then? Early in the game (on lower levels), I would sometimes add workers/settlers from nearby cities to boost my capital's population up if I wanted to speed up the process of building a wonder (like the pyramids, for example). Now why shouldn't I be able to do that post-hospitals to get a wonder faster if my city needs to be working more production tiles?
I like the idea of setting maximum city size at say, 60 (with this adjustable in the editor, of course). To get to size 60 you would need every single tile worked by that city and it being irrigated, railroaded, flood plains, with a bunch of wheat (nearly impossible to have that perfect food city). With a city maxed out at size 60, you would need so many more of these 'specialists capitals' to gain any real points, and for each one you have, you start losing even more scoring potential than just having one. To get 3600 'free specialists' I would need 60 'specialists capitals'. Thus, I would be needing to build 60 workers/specialists per turn just to keep up with starvation! I guess this still will net some more points, but a heck of alot more headache on someone trying to pull this off, with diminishing gains in score.
