Please keep things positive. Best advise I believe is to try out different sites. Find what works well for you. If you don't like it, don't go back and try another site. Nothing says you only have to play on 1 site. At one time, I played on about 6 different turn-based game sites.
Vikings: Go to the Zynga forums - they have an "ADD ME" area, where you can without signing up read and invite others who have wrote on the board - or join their forums and post your own "ADD ME".
For my Facebook Mafia Wars, I have 1,700+ players in my mafia - and almost all of those invited me when I posted in the ADD ME, plus posted in other areas on the forum with the add me in my signature.
I don't play the Mafia Wars much anymore so I removed all my none-true friends.
Note 1: Once you add someone to your mafia, you can remove them as a Facebook friend, BUT you will not be able to help them in missions & they can't help you.
Note 2: If you want to keep your Mafia as Facebook friends, you can play with your Facebook privacy level to basically block everything so they see nothing of your personal information.
