Blog comment spam - question

[Robert Holbach]

Hello

I'm one of the people administering the blog about our student portal. Part of that includes approving or deleting comments that are submitted. Recognising comment spam is not always entirely obvious - and in the last two days, we've been receiving comments that we're not sure about.

Usually, when we see comments like "Great post! Just wanted to let you know you have a new subscriber- me!" these are spam - the website the person enters will try to sell viagra or get rich quick schemes. Now we've received two similar, generic, positive comments, both of which have entered google as their sites. I presume Google isn't scared enough of Bing & Wolfram Alpha to stoop to comment-spamming yet ;-).

The email addresses of both comments end in cndnsfive.cn, so I'm pretty sure they're spam (as we're in Wales, not Canada), but I can't see how the spammer would benefit from us posting the comment...

Is there a different type of comment spam I'm unaware of? Do they have anything to gain (or we anything to lose) by having these comments visible on the site?

Thanks in advance for any advice

Robert

I see this every once in a while, too. I'm not sure exactly what the story is behind this type of stuff.

My theory is that it's kind of a "testing the waters" type of thing. There is some blog software that, once a comment is approved, other comments from that user will no longer go into moderation. I think it's possible that may be what this is about. Once you approve their initial comment, they can then come back and spam the heck out of your blogs without having to worry about things getting caught up in moderation.
