Getting Friends... Does it still work?

Can someone let me now if using an email address generator program to generate email addresses and then import the email address in to facebook still work in getting 5k of likes? I understand FB limits importing contacts to
5k. I should spread it over 7-10 days to be safe.

If this still works, any recommendations on an email address generator program?

Is there anything I need to do so that I do not lose my account?

Thanks in advance...

it is not really working man plus fb is very hard on the emails now so be very care full you might loose your acct
