Conditional Template Problem

[NP Carling26]

Basically we are using a One touch spam and clean modification from this site to clear spam bots and other such members from our forum. As it is sometimes necessary to delete accounts with 0 posts for such things as spamming in private messages, I tried to add a conditional to fit the requirements which enables this hack.

So far this is what I have in the template of MEMBERINFO:

PHP Code:

<if condition="is_member_of($bbuserinfo, 5,6,7)">
<if condition="$bbuserinfo['posts'] <= 50">
<li class="thead"><a href="misc.php?$session[sessionurl]do=spamcleanconfirm&amp;u=$userinfo[userid]">$vbphrase[spammer_ban_member]</a></li>
</if>
</if> 


Basically the less than/equal to 50 posts doesn't work. It will either show the modification on everyone's page or not show it at all if I make it "<51" instead.

If anyone could give me a solution that would be fantastic! Also there is a condition that the user has to be registered 30 days or less and if you could help me with that it would be amazing, if not don't worry about it too much

Also if it's worth mentioning we are running 3.8.4 patch 2.
