Some places where generation will gravitate to:

1) places where it's cheapest or free

2) people who want to help for idealogical reasons

3) people who want to get some coins without the inconvenience of doing a transaction to buy them

There are legitimate places where it's free. Generation is basically free anywhere that has electric heat, since your computer's heat is offsetting your baseboard electric heating. Many small flats have electric heat out of convenience.
