I’m getting loads of comment spam of late that is not bot-produced, but rather manually added, designed to generate google juice for some commercial site by taking advantage of the misimpression that this blog is a “do-follow” rather than a “no-follow” site. You might see an example of that in the comment most recently left on the MediaCommons post; the comment’s “author” was originally listed as something akin to “Buy My Product!”, and of course the URL given was the product’s website.
So here’s the deal: if I think your attempt to place an ad on my site is no more than that, you’re getting relegated to the spam bin. If I actually think the comment has some value despite being a lame attempt at increasing your page rank, I may keep it, but I’m deleting your author name and URL.
But let me clear up this misimpression here and now: this site does use the no-follow tag in all its commenter-added links. So please just save us both the trouble and stop. Thanks.
