Spam Comments


Spam Comments – we all get them

Rubber-stamp SpamHow 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

Do not  followSpammers 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.

  1. I started a blog 3 weeks ago and posted a few content and from three days ago I started getting annoying “Very nice I will bookmark it” type of comments. I am really discouraged due to this Nice kind of spammers. How do I differentiate between genuine comments and these spammers?
    Thank You.

    • @Shirish
      Good article you wrote about your spam comment experience at “How to Deal with Spam Comments
      How to differentiate between spam comments and the other kind… You pretty much have the idea with the examples in the article mentioned above. The famous “I like etc…” and “Your site has a bug in browser x…” are some of the classics.

      The things I look for include;

      • Is the comment about the subject of the article? Does it add to the subject, offer alternative viewpoints, support or criticise? Invite further discussion about the subject? If not – then it’s spam
      • Should the contact form have been used instead? The “bug report” comment is one that should be sent by contact form if the writer is genuinely reporting an issue with the site.
      • Are there links to irrelevant websites, or articles unrelated to the subject of the post and comment.
      • Does the comment poster have a genuine identity e.g. e-mail address? I often send a test e-mail – from an address used only for such things (who want’s their main e-mail added to a possible spammer’s database). A delivery failure usually means the address is faked.

      Apart from these obvious spam attempts, it’s a matter of judgement. Occasionally on some of my other (self-hosted) sites, I get a comment that may be considered relevant, with a link to an irrelevant site or article, or to a site with unsuitable content (examples of type of content I will not allow links to) . In this instance I sometimes remove the link and approve the comment.
      Self-hosted WordPress increases the options to manage the type of irritating comments you mention. The NoSpamNX plugin works similar to the default WordPress keyword filter, but instead of sending the comment to moderation, blocks it completely.

  2. Nice post…Being knew to this blogging thing, I was wondering about these sblogs…they can be very annoying to sift through!! But it’s good that if you miss one there is no added value of backlinks for those spammers.
