<h1>Travel platform's viral weekly giveaway must clear contest rules, avoid illegal lotteries, protect user data, and truth-in-advertising</h1> A travel platform's viral weekly giveaway campaign offers free stays to users who engage on social media and complete entry steps, promoting flexible short- and long-term bookings. Legally, the campaign implicates promotional and consumer-protection rules: organizers must ensure clear, accessible contest terms, transparent winner selection, and compliance with sweepstakes/lottery laws to avoid being characterized as a prohibited game of chance. Data-privacy obligations apply to collectees' personal information and to any linked landing page. Advertising must not be misleading about availability or pricing, and platform and social-media terms may restrict required actions (e.g., tagging, following).
