CSS selector to separate posts by current user

Development

Oh, just came here to post the js solution. I made a group called hidelikes and this js hides the who-liked for all group members for their own posts.

<script type="text/discourse-plugin" version="0.8">
    $( document ).ready(function() {
        let currentUser = api.getCurrentUser();
        var groups = currentUser.groups;
        var userID = currentUser.id;
        const hidelikes = groups.some(g => g.name === 'hidelikes');
        if (hidelikes) { 
               $('<style>').text('.boxed.onscreen-post[data-user-id="' + userID + '"] .who-liked{display: none;}').appendTo(document.head)
         }
    });
</script>

Obviously if you want to do it for all users just scrap the groups part
