Yep. If you're on the mobile site, going to any showsinglepost page leads you to a page with nothing but a nice white color. The entirety of the page's code is:
<html>
<head>
<style type="text/css">
:root #header + #content > #left > #rlblock_left
{ display: none !important; }
</style>
</head>
<body></body>
</html>
