-well i have not tried this but to disable any link on a post appearing you can go to settings>disscussion and then change the number of links to 1. So that you arent totally stripping links and only trying to only allow approved links like youtube.com from appearing.
Hold a comment in the queue if it contains [1] or more links. (A common characteristic of comment spam is a large number of hyperlinks.)
yes i know this is usually for comments but ive read some of these settings are either working on bbpress now or in the future.
-you can also just strip the links from either working by using this function.
plop it into your child themes funcitons.php or a functionality plugin.
add_filter( 'bbp_kses_allowed_tags', 'ntwb_bbpress_custom_kses_allowed_tags' );
function ntwb_bbpress_custom_kses_allowed_tags() {
return array(
// Links
'a' => array(
'class' => false,
'href' => false,
'title' => false,
'rel' => false,
'class' => false,
'target' => false,
),
// Quotes
'blockquote' => array(
'cite' => true,
),
// Span
'span' => array(
'class' => true,
),
// Code
'code' => array(),
'pre' => array(
'class' => true,
),
// Formatting
'em' => array(),
'strong' => array(),
'del' => array(
'datetime' => true,
),
// Lists
'ul' => array(),
'ol' => array(
'start' => true,
),
'li' => array(),
// Images
'img' => array(
'class' => true,
'src' => true,
'border' => true,
'alt' => true,
'height' => true,
'width' => true,
),
// Tables
'table' => array(
'align' => true,
'bgcolor' => true,
'border' => true,
),
'tbody' => array(
'align' => true,
'valign' => true,
),
'td' => array(
'align' => true,
'valign' => true,
),
'tfoot' => array(
'align' => true,
'valign' => true,
),
'th' => array(
'align' => true,
'valign' => true,
),
'thead' => array(
'align' => true,
'valign' => true,
),
'tr' => array(
'align' => true,
'valign' => true,
)
);
}
you might just delete all of the code specified for the a tag too and you will be fine
delete
// Links
'a' => array(
'class' => false,
'href' => false,
'title' => false,
'rel' => false,
'class' => false,
'target' => false,
),
