Have you seen this before?
one of my clients has a wordpress blog he runs himself and is getting a comment spam loop.
I haven't seen it quite like this before. Here is basically what is happening.
He writes an article
The first part of the article if copied onto another site, with a link back to the full article.
Then a comment is left from the copy site, with the author link back to the copy site.
The text of the comment is the copied part of the article and often contains the link, which is where the comment is posted.
A strange loop. Mostly I'm wondering how are they copying the article. I'm assuming from RSS. Any ideas how to prevent any unwanted copying?
It can't be good for SEO either, since the content shows up 3 times, all linking back to the original.
