What are the limitations or changes in Facebook's policies that may affect the functionality of apps that require users to like a page?

Facebook has recently updated its policies to restrict the use of incentivizing users to like a page in exchange for rewards or access to content. This change may affect the functionality of apps that rely on this practice to grow their audience or engagement. To comply with Facebook's policies, developers should focus on creating quality content and engaging experiences to attract users to like their page organically.

// Example code snippet for creating engaging content to attract users to like a page
$pageContent = "Check out our latest updates and exclusive offers! Like our page to stay connected.";
echo $pageContent;
