Mysterious Leaflet Distributors Encourage Referendum Voting with Misleading Instructions

Clever trick discovered! Unknown individuals are distributing leaflets to villagers, inviting them to participate in the referendum with misleading voting instructions. The leaflets circulating in Suphan Buri province suggest marking a check mark in the 'Approve' column, which would actually invalidate the ballot. Official referendum rules require voters to use only an X (cross) mark, and any other symbol will render the ballot void.
