Why you should enable Comment Verification on your blog
Have you been noticing the kind of comments that go: "Hi, I really liked this. I have a site on [something related to your post, with a link]. Do visit my blog when you have the time."
That's comment spam enabled by programs that search for relevant content and then slip in a comment. Thought we'd share an email with you, one that came in to one of my friends on the KatrinaHelp.
Sorry to have to bring this to your attention. I have just been revisiting the tsunami blog to catch up after being offline for some time.
There is new software on the market that is capable of automatically submitting comments on random blogs for the purposes of getting backlinks for SEO. This software can be tweaked to only post on blogs in certain categories which can be set by the software operator. There are a few versions ,but new kid on the block is marketing hard. It has been aggressively marketed over the last 2 months. See holygrailofmarketing.com (Blogsubmitter Pro)
Yeah, we know. We deliberately didn't make the URL clickable.
Experienced blackhat SEO sploggers are setting the software to post comments on blogs which are popular and spidered regularly with strong rich content.
Heh heh. We wondered why our humble blog was being picked on. SEA-EAT we can understand. But us? Now we know. We have strong rich content, y'hear? Heh.
As disaster sites are in the news again, some people are using this software to post comments to posts on these blogs purely for the purposes of marketing their products, sometimes often illegal warez, gambling, porn sites, but mostly opportunistic marketers trying to take advantage of the link to a popular blog (which the software pings automatically after the comment is posted) to get the backlink spidered.
The nofollow tag stops google from following it , but according to users does not stop yahoo and others.
Webmasters who monitor the comments usually delete them quickly. To prevent autosubmitting most suggest adding (not sure what it's called) the box where you have to copy a graphic distorted letter image into a form to prove you are a human not a bot.
You can do this in blogger under settings > comments. Blogger calls it "comment verification." Turn it on.
See the range of examples on comments to the post on Tsunami Blog Re Blogging for Disaster Relief.(also previous post and maybe more)
I am a marketer myself, and own a copy of this software, which like any tool can be used responsibly or not.
But it made my blood boil when I saw the comments on Tsunami Blog.
Can somebody take a moment to delete these leeches sucking on the popularity of the disaster blogs, and using the victims newsworthiness to line their own pockets rather than assist those who need it!
Well, leeches, suck no more on this disastrous blog. We have comment verification turned on. Apologies to our regular commenters. Plis to adjust.
