180solutions Domain Exclusion List - Change Analysis
The Effect of 180solutions on Affiliate Commissions and Merchants - Ben Edelman

As discussed in Responses from 180solutions, Affiliate Networks, Affiliate Merchants, Affiliates within The Effect of 180solutions on Affiliate Commissions and Merchants, 180solutions can disable its targeting (and its advertisers' targeting) of specified domain names. This page reports the specific domain names 180 has chosen not to target.

I have observed and preserved 180's domain exclusion list from time to time, beginning in July 2004. This page tracks the list's various changes.

For selected domains, I have listed a classification. Some domains seem to be excluded because they are 180solutions itself, or 180's business partners, neither of which 180 apparently seeks to target with its popup ads. Other excluded domains are affiliate merchants; my earlier research documents interference by 180solutions (and its advertisers) with certain affiliate programs. Note that classification entries are not yet complete. The table below reports my classifications of the domains listed in the November 1, 2006 exclusion list:

Classification	Number of Domains
180solutions Domains & 180solutions Partners	78
LinkShare Merchants	0
Commission Junction Merchants	1
Performics Merchants	0
Independent Affiliate Merchants	113
Government/Information Web Site	1
Ad Syndication / Pop-Up Domains	10
Unknown / No Classification	45

During much of 2004 through early 2005, 188 LinkShare merchants were present on 180's exclusion list. However, in my current testing, those merchants are no longer listed on 180's exclusion list.
