I have an Auto Blog that lists Ebay Auctions. There is basically no Content, just a small Image and the Headline of the Auction. Only 2% of the Postings are in Google Cache. So I was wondering if it actually might be a good idea to allow Comment Spam. Right now I use the WP Plugin Antispam Bee. But wouldn't allowing Spam Comment actually turn my Blog into a Content Blog from a no Content Blog and help in SERP? Just wondering.
