Hi Julia,
I know from our earlier conversations your/
AW's intentions and honourable but I think the agreement is doomed to failure simply because it's a gentlemans agreement.
I've never bid or SEOed any of our sites to rank on any rivals sitenames (trademarked or not) and I'm happy to publically declare that I would only ever consider doing so if I found a site abusing the mutual respect most long-standing affiliates have always had for each other.
One the few occasions I have found sites bidding on our sitenames I've found the best way to resolve the problem has been to approach the site owner directly.
Sites which have fallen foul of this previously unwritten agreement between established affiliates will naturally see this agreement in a more positive light in an effort to get a monkey or two off their backs but for people like myself there's no benefit to participating and to that extent I share Lee and Buds reservations.
A mandatory agreement enforced across affiliates and networks would be cool but in reality it isn't ever going to happen so having declared my non-agression pact with the rest of the affiliate world for now I'm content to fight my own battles.
Perhaps public declarations like mine would be an alternative way forward?
