I got a two signature limits (max. number of lines and max font size) in my board which do work quite good.
These are both adjustable in the Admin CP, 0 does mean no limit.

Maybe it is useful for others too, therefore I'm gonna post the code here.

In the User Profile Options section of the Admin CP create the settings

• maxsiglines
• maxsigfontsize

In Phrasegroup Front End Error Messages create the following phrses

• sigtoomanylines
• sigtoolargefont

In profile.php FIND

PHP Code:

if ($vboptions['maximages'] != 0) 


ABOVE that INSERT

PHP Code:

    // Signature Hacks
    require_once('./includes/functions_bbcodeparse.php');
    require_once('./includes/functions_misc.php');
    // Signature Hacks
    // Signature Limits Hack
    // Check max. font size
        if ($vboptions[maxsigfontsize] > 0) {
      // Make sure user does not user too large fonts
          $pattern = "/\[size=\+*0*[" . ($vboptions[maxsigfontsize]+1) . "-9]\].*\[\/size\]/si";
      $pattern2 = "/\[size=\+0*[1-" . $vboptions[maxsigfontsize] . "]\].*\[\/size\]/si";
      if (preg_match($pattern, $signature) or
          preg_match($pattern2, $signature) or
              preg_match("/\[size=\+*0*[1-9][0-9]+\].*\[\/size\]/si", $signature)
          
         )       {
        $preview = 'true';
        eval('$errors[] = "' . fetch_phrase('sigtoolargefont', PHRASETYPEID_ERROR) . '";');
      }
    }
        // Check max. lines
    $line_parsed_sig = parse_bbcode($signature);
    $siglines = 0;
    $siglines += fetch_character_count($line_parsed_sig, '<br');
    $siglines += fetch_character_count($line_parsed_sig, '<blockquote');
    $siglines += fetch_character_count($line_parsed_sig, '<pre');
    $siglines += fetch_character_count($line_parsed_sig, '<center');
        if (preg_match("/\<blockquote\>(.*)\<\/blockquote\>/si", $line_parsed_sig, $matches)) {
          $siglines += preg_match_all("/\n/si", $matches[0], $lines)+1;
        }
        if ($vboptions[maxsiglines] > 0 and $siglines > $vboptions[maxsiglines]-1)  {
      $preview = 'true';
      eval('$errors[] = "' . fetch_phrase('sigtoomanylines', PHRASETYPEID_ERROR) . '";');
    }
        // Signature Limits Hack 


Please note that this does not affect current signatures.
