How can Schleichwerbung (stealth advertising) be avoided in PHP forums?

Schleichwerbung (stealth advertising) can be avoided in PHP forums by implementing strict moderation policies that prohibit any form of advertising within forum posts. Additionally, users should be reminded of these policies and encouraged to report any suspicious posts that may contain stealth advertising. 

// Example PHP code snippet to prevent stealth advertising in forums

// Check if the post contains any suspicious advertising keywords
function check_for_stealth_advertising($post_content) {
    $keywords = array("buy now", "limited time offer", "exclusive deal");
    
    foreach($keywords as $keyword) {
        if (stripos($post_content, $keyword) !== false) {
            return true; // Stealth advertising detected
        }
    }
    
    return false; // No stealth advertising detected
}

// Usage
$post_content = $_POST['content'];

if(check_for_stealth_advertising($post_content)) {
    // Do not allow the post to be submitted
    echo "Stealth advertising is not allowed in this forum.";
} else {
    // Allow the post to be submitted
    // Process the post content here
}
