That's a spam referrer. Response from staff:
Thanks for reporting this - we are aware of this problem and are working hard to find a solution to fix it.
Some background: what you're experiencing is called "Referrer Spam", and it's an unfortunate side effect of the way statistics tracking works. Spammers take advantage of the referrer logs and visit your blog from phantom URLs that they are actually trying to promote, in the hope that you see them in your logs and click them.
In the meantime, you can rest assured that there is no security risk here, to you or to you blog. It's just an annoyance, but one we will hopefully be able to get rid of very soon.
These spam referrers do not in any way affect your blog's Google page ranking.
1. Do not click the links.
2. Do not post the URL or names of the site into forum threads.
3. Report all spam referrals to Staff directly .
