Social media has benefits but also risks to privacy and online reputation. While it allows connecting with others and sharing information, users must be aware that their digital trails and online interactions could impact them long-term. For example, a woman was fired after posting a racist joke on Twitter during her vacation. Her case shows that what users post online can affect future opportunities. It is important to use privacy settings, be cautious of what is shared, and avoid inappropriate interactions, as colleges and employers may now consider social media activity when evaluating applicants.
