fb is a social networking site,they want you to
stay on the site longer, so if you are posting links
and requests to people within moderation they
will support you.
However as Nicky said do it more subtly and
slowly by putting things of valuet in your posts.
Join groups that are relevant to your interests and
answer questions .
Also fill in all your information on your profile
fb will then start to refer poeple to you in your interest
All the best Brian.
