func containsForbidden(text string, forbidden []string) bool {
    lower := strings.ToLower(text)
    for _, w := range forbidden {
        if strings.Contains(lower, w) {
            return true
        }
    }
    return false

func main() {
    text := "This text contains a badword inside"
    forbidden := []string{"badword", "evil", "kill", "nasty", "terrible"}

    if containsForbidden(text, forbidden) {
