How bout this:

• Reciprocal link request pages coupled with existing reciprocal links to non-relevant sites.Thanks thecoalman
  
• No Privacy policy. (Debatable) (site-dependent?) (jdMorgan:The standard URL for your compact privacy policy is: /w3c/p3p.xml )
  
• Outdated copyright date or last modified date visible on the pages. (Debatable)
  
• error pages that don't send 404 headers or send content regardless of the page requested/querystring entered.
  
• Massive numbers of incoming links from link farms.
  
• dead/404ing links.
  
• High link churn.
  
• No published contact address, email address or phone number. (Debatable) (site-dependent?)
  
• A high bounce rate (surfers clicking back on their browser and selecting another search result).
  
• Too much duplicate content.
  
• Whois info for the domain which is the same as other domains previously penalized or banned. (Could also be true of adsense publisher/affiliate ID's and other identifiable footprints)
  
• Use of/links to affiliate programs that are known scams
  
• Domains previously used for spam or that are blacklisted.
  
• excessively long URI's/URL's (query strings or folder and file names)
  
• A high percentage of affiliate links vs regular outbound links.
  
• No / very few outbound links (depending on the site's type/niche).
  
• No / very few inbound links (depending on the site's type/niche).
  
• All inbound links are to homepage only (Debatable)(Site Dependant?)
  
• Outbound links to questionable/spammy/crap sites.
  
• [Matt Probert]The inappropriate or gratuitous use of profanity
  
• Too many spelling errors.
  
• Contains unrelated subjects (ex: a site that reviews toys and tries to sell insurance or viagra).
  
• Lack of interest from social bookmarking sites.
  
• MySQL or PHP errors in the pages
  
• [tedster]No real menu or information architecture -- just a laundry list of links going on down the page.
  
• [abbeyvet]relatively short pages/articles containing unnaturally high keyword density for their topic - almost always contain within them 2 or more large adsense or other advertising units.
  
• [steveb]Adsense
  
• [steveb]More than 25% links from blogs
  
• [steveb]No links to the site from any domain in the top 100 for a query where the page ranks in the top 20 for that query
  
• [mattg3]Small font size text framed by ads. Or big adsense blocks. I avoid them cause I am sue my users think too they are cr@p. Just disregard the heatmap.
  
• [buckworks]The drop list for the user to select their credit card expiry date still includes last year.
