Extermination penalties

[Oaty]

Well it just popped in my mind a good counter to exterminating a city. And since people want them heres an idea

After extermination there is an 100 percent income reduction for the city and is reduced by 5 percent a year. This would make it take 20 turns for this city to become fully functional again.

Or cause fear in all the new settlements and cause riots revolts for a few turns, income is usualy not a problem for me anyways

Crank up the amount of unrest in an exterminated city? Such that the increase in unrest from killing lots of people would be more than the squalor drop from the reduced population. Then that would make extermination useless for squalor control.
