Can somebody explain to me where this hex string comes from?

It has lots of matches on Google. Most of them are on blog comments. But they appear on valid comments, so I don’t think it is some marker string being used by spam bots.

    I think I have found the culprit: PHP Markdown. It uses some tricks using md5 hashes, including some handling of html tags.

    Look:

    $ echo -n '</p>' | md5sum

    I don’t know if the bug is present on recent versions of the WordPress Markdown plugin, however.
