The locking of maps at Malsingmaps was initiated by Anthony Yong while he was at Malsingmaps. This locking requires users to submit data before being eligible for the unlock key.
When Anthony moved to Malfreemaps he no longer locks his maps. This is to entice users to use Malfreemaps over the locked Malsingmaps.
Malsingmaps now gives out the unlock key to her users freely, not requiring any prior contribution.
