Probably just something like this:

PHP Code:

if (THIS_SCRIPT == 'report') 
{
  if (is_member_of($vbulletin->userinfo, a,b,c))
  {
    $vbulletin->options['emailfloodtime'] = xxx;  
  } else if (is_member_of($vbulletin->userinfo, d,e,f))
  {
    $vbulletin->options['emailfloodtime'] = yyy;  
  } else
  {
    $vbulletin->options['emailfloodtime'] = zzz;  
  }
}
