Meta Thailand announced that Take It Down, provided by the US-based National Centre for Missing & Exploited Children, has expanded the free service to Thailand.
The service could be used for free if the offending pictures or video clips were taken when they were not older than 18.
Meta Thailand said parents of young Facebook users must go to the Take It Down website and answer questions as required.
Parents can then upload photos or clips they suspect might have been shared on social networks.
Take It Down would then use a digital footprint to scan such photos or video clips and remove them.
Meta Thailand said if inapprpriate photos or clips belong to persons who are older than 18, they can use similar services from stopncii.org.
