The PageRank algorithm that Google uses seemed to be weird, and sometimes websites that contains virus and other malware appear at the top results (which Google should be trying to at least remove on their results). It really is not bitcointalk's fault if the certain topic is in there, and there's no way a post can be deleted here as long as it doesn't break any rules, even though the subject is misleading. How about contact Google on this matter and see what their say is?
