What are some potential drawbacks of using pre-made bad word filters in PHP?

One potential drawback of using pre-made bad word filters in PHP is that they may not catch all variations or misspellings of offensive words. This can result in inappropriate content slipping through the filter. To address this issue, you can create a custom bad word filter in PHP that includes a comprehensive list of offensive words and their variations. 

$badWords = array("badword1", "badword2", "badword3");

function customBadWordFilter($text, $badWords) {
    foreach($badWords as $word) {
        $text = preg_replace("/\b$word\b/i", "***", $text);
    }
    return $text;
}

$inputText = "This is a badword1 sentence.";
$filteredText = customBadWordFilter($inputText, $badWords);

echo $filteredText; // Output: This is a *** sentence.
