Brett Yount from Microsoft’s Bing Webmaster team has commented here and in a Bing Forum thread saying the issue with the fake referrers being generated by MSNBot has finally been fixed. By finally, I mean, an issue dating back over two years.

Brett said:

There are confirmed reports by webmasters that the issue is no longer being seen and that going forward their log files are no longer being polluted with fake referrer data.

I am happy to hear reports that this is fixed, but you can’t blame me for being a bit skeptical that this issue might creep up again. I mean, Microsoft fixed this issue at least three times in the past. I certainly hope it is fixed forever.
