I have an account with something like 1200 friends on it. I am inviting people to a page of mine and I did the sugg friend thing, I changed my profile picture, shared the link, and put it in my status. I got something like 75 users joined in the first day but it's very slow and I know low because people just aren't seeing it in the jumble of things.
Are the above ways a save method to post a message to the wall of all my friends without being banned? What specifics should i avoid so it's not banned?
