Is there a counter to the "CS worker steal" exploit?

They don't perma-DoW with you anymore but it begins to really be difficult to ally some of them if you enter in conflict at many occasions. Counting from the 2nd DoW, the cs influence is decaying much faster than the original state and for each DoW implemented.

At full war mode and few civs it's an advantage, but with longer games and more players you can be in some difficulties if you don't able to ally 2 or 3 of them for the long run for extra happiness and other stuff.

Does anyone know the formula for this or at least how it works? Does it decrease influence faster for all CS or just the one you DOW? Is it permanent or does it decrease over time? Do they forgive you slower or just drop influence faster? Does it count if you take them over?
