 It's a side-effect of having a website that redirects a number of pages to
 the same content, without a proper redirect HTTP Response Code (eg 301,
 304). It's a technique spam/link farms use a lot so Google basically
 outlaws it (they call it Cloaking). I found out about this issue because
 Google sent me an email saying my blog had been flagged as Malware because
 of this behaviour. Here's the link they provided with more info:
