Final answer:
It's false that implementing an effective social media strategy only requires awareness of legal challenges; ethical considerations are also crucial due to the complex issues raised by content and data usage on social media platforms.
Step-by-step explanation:
To implement an effective social media strategy, one must be aware of both legal challenges and ethical considerations. The assertion that only legal challenges need to be considered is false. Social media platforms are under scrutiny for the content they host, which can include hate speech, disinformation, and the potential for misuse through technologies like deepfakes.
With social media's impact on democracy, it is crucial for strategies to address the spread of fake news and ensure user data privacy. Social media is also used for political participation, and strategies must navigate complex legal and ethical landscapes involving freedom of speech and reach, among other issues.
