THE Davao City government has warned the public against the membership recruitment activities of groups Mindanao Grassroots People’s Coalition, Caesar City Corporation, Mindanao Bunkers Monetary Council, Mindanao Indigenous Sovereign People for CCC, Mindanao Golden Mind Filipino, Mindanao Filipino Religious Sectors, and the Mindanao Filipino Youth Leaders for CCC. The Davao City Anti-Scam Unit has already conducted a preliminary background check on these groups and “uncovered a possible pyramiding scam,” the local government said. The matter has been endorsed to the National Bureau of Investigation for appropriate and urgent action, it added.
