Dark Patterns – User Interfaces Designed to Trick People [video]
One pattern that I consider "dark", but don't see in this list, is using loaded options on a dialog box.  One that I often see in apps is like:<p><pre><code>    Rate our app!  
    <OK> <Not Yet>  
</code></pre>
Those really get under my skin because the developer is clearly trying to play a psychological trick on me, but it's so brazen and obvious that it just pisses me off.  And bigger companies do it too (e.g. Google).
