I was reviewing the flak logs the other day (chasing an unrelated issue) when I noticed lots of requests with additional parameters, like utm_campaign=twitter. Huh? I’m not running any campaigns. GTFO.

I find these tracker tags in URLs annoying when other sites do it. It’s not the tracking that bothers me, but the fact that the URLs end up being long and ugly, and it means there’s several URLs for the same content. I much prefer canonical URLS. Different tracking URLs break duplicate detection on various link sharing sites, and trick the browser’s history feature. Boo.

Of course, it’s your site, you do what you want, but this is my site, so don’t dick with my URLs. To that end, flak now filters out extraneous parameters by driving you through a bounce screen. Hopefully this prevents the further sharing and posting of the infected URLs.

Try it out.
