Clickbank affiliates in URL filter

Can't seem to get them to work

[MaxMaxMax]

There's a particularly inappropriate ad I'm trying to stop appear on one of my sites. It's of the clickbank affiliate link format, e.g.:

hop.clickbank.net/%3Faffiliate/merchant

Though I added it to the URL filter a while back, both in the above form and as:

hop.clickbank.net/?affiliate/merchant

...the ad still keeps showing up with that URL.

Anyone got an obvious suggestion before I trouble those kind folks at Google with my problem?

Could they be having trouble with the? variable on the filter list? Filtering clickbank.net would work, but would filter out all clickbank affiliate links for you. If that isn't an issue, just go and filter the whole domain.

Otherwise, I think it will be a question for the Google technical team. If? is the issue, perhaps they aren't even aware of it.

Thanks Jenstar. In my case, filtering out all Clickbank urls wouldn't be ideal, but not a great loss, so that sounds like a good solution.
