<h3>History</h3>
</div>
<div class="taskboxtext">
<p>MSN Messenger, now called Windows Live Messenger, is a freeware instant messaging client that was developed and distributed by Microsoft in 1999 to 2005 and in 2007 for computers running the Microsoft Windows operating system (except Windows Vista), and aimed towards home users. It was renamed Windows Live Messenger in February 2006 as part of Microsoft's Windows Live series of online services and software.</p>

<h3>Censorship</h3>
</div>
<div class="taskboxtext">
<p>MSN censors messages containing particular fragments of URLs. Previously, the message would simply be dropped with no indication to either side that it went away; now, at least, you get an error message (inline in the message view).</p>
<p><strong>Pieces of text that are known to cause MSN to throw a message into the <a class="ext_link" href="http://en.wikipedia.org/wiki/Memory_hole">memory hole</a></strong></p>
<p>The most common ones that we know of are:</p>
<ul>
<li>.info</li>
<li>profile.php? (including ‘?’)</li>
<li>download.php? (including ‘?’)</li>
<li>gallery.php</li>
<li>pics.php</li>
<li>ListAllTopics.php</li>
<li>.scr</li>
</ul>
