See timcederman's post below. Reviews can, and do disappear apparently. Yelp admits the "spam algorithm" can be aggressive on new reviewers.<p>&#62;&#62;"[The] spam algorithm can filter based on how established user is. [Your post was] not deleted &#38; can re-appear on biz page. Still live on your profile."<p>It sounds fishy to me. Who cares if the review is "still live on your profile" if it's not live on the business page. It doesn't sound like a spam filter to me, it sounds like selective removal of reviews.
