Online challenges are activities or tasks that people participate in through social media platforms. These challenges often encourage users to complete specific actions, share their experiences, and tag others to join in. They can range from fun and harmless activities, like the Ice Bucket Challenge, to more serious issues, such as raising awareness for a cause. While many online challenges promote creativity and community engagement, some can pose risks. Certain challenges may encourage dangerous behavior or lead to harmful consequences. It's important for participants to consider the potential impact of these challenges before joining in and to prioritize safety.
