Yes it is agianst their TOS and AUP etc... You don't even want to really talk about it... kind of a hush hush in all reality. Yes google does go to forums and search to see what is going on. If they have a hint of anything they will disable the account and say good bye
which is good. Kind of like the Maffiat keep your MOUTH HUSH HUSH or we will wack your knees or break your teeth in so you don't speak again
