So i figured out how to get other people to add you, via mafia wars and farmville and other Add me groups. But i don't get enough friends, only 20-30 per post in group. The thing is i don't know how to safely add other friends. I know that there is and option to harvest email addresses on internet and add them via txt file. But i don't get enough emails harvested and it would look suspicious if i overdo it. So what is safe way to add friends?
