Can you stop guest to see the most contribution list?

[fairlight 3]

Like the list below? 

on my forum, guest couldn't see the post list(I forgot how I did that...) but not the popular contributors list

also, in my case, I didn't use the default system build "popular contributors" block, Im using the block from "Members shop" 

Please help, thank you!!

{{$pointsName = \IPS\Settings::i()->ms_points_name;}}
<h2 class="ipsType_sectionTitle ipsType_reset">
    {lang="ms_most_points" sprintf="$pointsName"}
</h2>
<ol class='ipsDataList ipsDataList_reducedSpacing'>
    {{$idx = 1;}}
    {{foreach $mostPoints as $members}}
        {{$member = \IPS\Member::load( $members['member_id'] );}}
