Spam Comments – we all get them
How many bloggers have never had their comment form used by spammers? Very few I would say.
Perhaps the number of spam attempts on our comment forms is an indication of how succesful our blogs are. At least it seems that the sheer number of spam comments increases as our blogs become more established. New blogs take a while to attract spammers, older ones with plenty of content and readers get more.
Spam Comments for Backlink SEO
Many of these spam comments seem aimed at generating backlinks to the spammers website(s). Invariably there will be at least one such link, almost invariably to some product page or site selling something (usually junk).
Another type of link refers to blogs on wordpress.com. These are ‘Spam Blogs‘. (Splogs) No (or very little) content of value, often just a few words, and a link to a web site where something is for sale. Very often splogs consist of just a single post, even if the blog is several months old (or older) These spammers have at least taken the time to sign up for a wordpress.com account, to circumvent restricted commenting (where guest account has been disabled).
Spam Comments Useless for Backlinks
Spammers intending to get backlinks to their sites probably do not realise their links they load into our comment forms have no value as backlinks. The good guys at WordPress.com have thought through the problem and have included no-follow code for links in comment forms, both for links contained in the body of the comment, and for the URL in the commenter’s identity. The following answer to my question to wordpress happiness engineers explains this clearly…
We don’t nofollow the whole comment section (so comments themselves are indexed), we just nofollow the commenter’s link and any links made within the comments (so they don’t earn any page rank points).

So the only benefit the spam link has is possibly to generate a bit of traffic to the site.
My suggestion for any blogger wanting to limit spam is simple, disable the guest commenting feature. Anyone who has a genuine comment to add to your post can still comment using their wordpress.com, Facebook or Twitter identity.
Spammers will still try to get their rubbish posted, but you will not end up with 50 or more such inane remarks and links in your pending moderation box. and if you do get comment spammed, don’t follow the links – that is exactly what the spammer wants you to do.
