find in MEMBERINFO "<!-- current activity -->" and add a condition, like the one I added below. It works

PHP Code:

                <!-- current activity -->
                <if condition="$prepared['lastactivitydate'] OR $prepared['action']">
                    <div class="alt2 smallfont block_row" id="activity_info">
                        <if condition="$prepared['lastactivitydate']">
                            <div id="last_online">
                                <span class="shade">$vbphrase[last_activity]:</span> $prepared[lastactivitydate]<if condition="!$show['detailedtime']"> <span class="time">$prepared[lastactivitytime]</span></if>
                            </div>
                        </if>
                        <if condition="$prepared['action']">
                            <span class="shade">$vbphrase[current_activity]:</span> $prepared[action] $prepared[where]
                        </if>
                    </div>
                </if>
                <!-- / current activity --> 


and add

<if condition="is_member_of($vbulletin->userinfo, 6, ....)"> after "<!-- current activity -->". Remembering to close it with </if>
