Shouldn't there be an else branch like:

PHP Code:

$doignore[uid] = array(ignoreid1, ignoreid2); 

if (array_key_exists($bbuserinfo['userid'], $doignore)) { 
  $bbuserinfo['ignorelist'] = implode(' ', array_merge(explode(' ', $bbuserinfo['ignorelist']), $doignore[$bbuserinfo['userid']])); 
}
else
{ 
  $bbuserinfo['ignorelist'] = implode(' ', $doignore[$bbuserinfo['userid']]); 
}
