What are the pitfalls of Doppelpostings in PHP forums and how can they be avoided?

Doppelposting in PHP forums refers to the act of posting the same content multiple times, which can clutter the forum and annoy other users. To avoid this, you can implement a check in the forum submission process to prevent users from submitting duplicate posts within a certain timeframe. 

// Check if the same post content has been submitted within the last 5 minutes
if($last_post_time > time() - 300){
    echo "You have already posted this content. Please wait before submitting again.";
    exit;
}

// Save the current post time for future checks
$last_post_time = time();
