Competitive adfilter...

[markus007]

I've counted 3 sites that have been blocked for months are suddenly starting to show again on mine. It is happening when long description is used, or a single ad is taking up the space of 2 or more ads.

I'm seeing blocked sites showing up as well.

I think you have to block both www.somesite.com and somesite.com and whatever subdomain you see them using. Not sure though.

Yes, markus007, I can confirm that. Their filter system is either buggy or they are "testing" how much more money they can earn if they occasionally stop filtering.

And yes, domain.com has been on my filter list for months and, yes, I checked the actual ad URL in the source code of the page and in the preview tool. Yet, www.domain.com ads were served on our site.

I reported that to them and they apologized and said that they'd take "extra steps to ensure that www.domain.com ads won't be served on our site". I haven't seen these ads since then.
