More than 200 supporters, mostly women, have concentrated their efforts on remote areas without television or e-mail, which have still not been reached by the worldwide campaign spearheaded by Kate and Gerry McCann.
The private detective agency hired by the couple believes Madeleine was probably smuggled from Portugal to Morocco after she was abducted on the orders of a paedophile network.
Metodo 3's confidential hotline in Spain has been inundated with more than 350 calls since Kate and Gerry McCann's heartfelt Christmas Eve appeal to their daughter's captor, and it is believed that some of the calls have given information related to Morocco.
Detectives have already spoken to several witnesses who believe they saw Madeleine in North Africa in the days following her disappearance on From Vanessa Allen in Praia da Luz May 3.
