XF 1.5 Add noffolw to profile link in thread

[Biarritz64]

hi,

i would like to add a "noffolow" for profile link and avatars (in the thread)
Any idea

i found this and don't know how to edit in message_user_info

require css="message_user_info.css" />

<div class="messageUserInfo" itemscope="itemscope" itemtype="http://data-vocabulary.org/Person">   
<div class="messageUserBlock {xen:if $user.isOnline, online}">
    <xen:hook name="message_user_info_avatar" params="{xen:array 'user={$user}', 'isQuickReply={$isQuickReply}'}">
        <div class="avatarHolder">
            <span class="helper"></span>
            <xen:avatar user="$user" size="m" img="true" />
            <xen:if is="{$user.isOnline}"><span class="Tooltip onlineMarker" title="{xen:phrase online_now}" data-offsetX="-22" data-offsetY="-8"></span></xen:if>
            <!-- slot: message_user_info_avatar -->
        </div>
    </xen:hook>

<xen:if is="!{$isQuickReply}">
    <xen:hook name="message_user_info_text" params="{xen:array 'user={$user}', 'isQuickReply={$isQuickReply}'}">
        <h3 class="userText">
            <xen:username user="$user" itemprop="name" rich="true" />
            <xen:if hascontent="true"><em class="userTitle" itemprop="title"><xen:contentcheck>{xen:helper userTitle, $user, 1, 1}</xen:contentcheck></em></xen:if>
            {xen:helper userBanner, $user, 'wrapped'}
            <!-- slot: message_user_info_text -->
        </h3>

i already add /members/ in robots.txt and disable profile view for guest.

Yhank you
