Backup Backup Backup.
It seems that google have written to all adult bloggers with an upcoming change in the T&Cs preventing any attempt at making money our of an adult blog. We haven't had any email, but we don't have any affiliate links running from our blog so we shouldn't have any issues - but we are about to launch an affiliate program - so it might have an effect on you if you are running a blogger blog and have affilate links.
So backup backup and backup again!!!
