How to accidentally erase your ad filter

When you’re adding sites to the Google Adsense “Competitive Ad Filter” please do not do what I just did.

As my filter has the maximum 200 urls I have to delete entries before adding new one, but I had deleted a couple of urls so I thought I’d have space for just one more slightly-dodgy low paying ad site. Unfortunately I didn’t and the familiar “Too many lines” error showed.

Normally I would search out another url to delete but I wanted to be done with it and not bother with my last change so I hit return on the url, this url, – thinking that it would reload the old list. It certainly did. It brought me back to day 1 when I had no entries in the filter! You know that sinking feeling? That moment when something has gone really wrong? That was me a few minutes ago.

Thankfully hitting BACK on my browser and confirming the POST operation restored the list and I quickly removed the offending LCPC site. Phew.

Someone should tell Google, this would be a rather quick and easy way for a malicious someone to mess with a person’s filter. They should check for the existance of some POST variables before overwriting the filter. It’s a bug!

Simply because a blog post isn’t a blog post without a link, here’s where I talk about my competitive ad filter. MFA and LCPC sites galore. The MFA sites listed in this post finally made it into the ad filter this morning.

  1. For whatever good it’ll do. My CPM has been much lower over the last 5 days than the previous 2 months and it’s bugging me that these low cost ads are getting through. It’s probably a seasonal thing.
