Hi,
Looks like those are some sort of unfiltered mentions. I guess the only way to fix them is by using a custom code. Try adding this custom code to the functions.php in your theme/child theme directory. Before editing, please make sure to have a full site back-up just in case!
add_filter('asp_results', 'asp_remove_peepso_mentions', 10, 1);
function asp_remove_peepso_mentions($results) {
foreach ( $results as $k => &$r ) {
$r->title = preg_replace('/@peepso_user_[0-9]{1,5}\((.*?)\).*?/i', '$1', $r->title);
$r->content = preg_replace('/@peepso_user_[0-9]{1,5}\((.*?)\).*?/i', '$1', $r->content);
}
}Please be careful, I have not been able to test this code yet.
As for the images, unfortunately there is no way of getting those at them moment, I am sorry.
