I figured it would be a smart choice to use some FB accounts to invite all friends to groups that I've created. It would make the groups more targeted in terms of demography and have full control over the administration of open groups. For instance, 5 accounts with 4500+ friends invite to one group means 22000+ members in just a couple minutes. However, I find it a bit complicated to quickly load up an account with 5000 real friends (USA, UK, Canada targeted) with out using sexy girls profile pictures. In fact, most female users wont be interested in these accounts and are probably just removing the friend request or even worse reporting the accounts. Are there any quick ways (blackhat or whitehat) to gain up to 5000 friends in a short period of time?
