<h1>Nonprofit launches nationwide Smile Walls campaign using public and private sites, raises permissions, permits, content moderation, and privacy issues</h1> A cleft-focused nonprofit launched a nationwide public-awareness campaign installing interactive 'Smile Walls' at partner hospitals, schools, corporate sites and public transit locations to encourage community messages and art supporting children with cleft conditions. The campaign, timed to World Smile Day, invites organizations and individuals to create physical and digital walls and to contribute messages; it highlights prevalence statistics and promotes donor and volunteer engagement. The initiative involves use of public and private sites and third-party partners, implicating routine legal considerations such as site permissions, local permits, content moderation, and privacy consents for posted contributions.
