Set nofollow tag on the link field of viewlisting template

[ronin +]

As by title,

I'm trying to set the NOFOLLOW tag on the viewlisting template, to avoid user "spam" my web site just to insert backlink to their website..

I found the solution, but I need a confermation, to be sure this NOFOLLOW don't ruin internal links, or others link..

The file in plugins\modifier.linkurl.php, line 62

from:

PHP Code:

$string = preg_replace($pattern,"'$1<a href=\"$2$3\" title=\"$2$3\" target=\"_blank\">'.kuerzen('$2$3',$length).'</a>$4'",$string); 


to:

PHP Code:

$string = preg_replace($pattern,"'$1<a href=\"$2$3\" title=\"$2$3\" rel=\"nofollow\" target=\"_blank\">'.kuerzen('$2$3',$length).'</a>$4'",$string); 


Anyone, can give me any confermation this change ONLY affect the link in the viewlisting page (that is: the link user can inserit in their listing)?

Thanks for reply,

Ronin
