What it boils down to is interpretation of this by Amazon's staff (where I highly suspect there's a language barrier causing this, given Amazon cheaping out on support):
(p) You will not include any Special Links in any content that you place on an Amazon Site (for example, in connection with any advertising service available through an Amazon Site or in a customer review, forum, Wish List, guide, or any other customer-generated context available on an Amazon Site).
And from a
post above which might also be a clue:
What’s next?
If you own the forum site, kindly resubmit your application and remember to ensure your email ID matches with the domain name. You will be paid for any outstanding fees accrued prior to this notice. You’re welcome to reapply once our other program requirements are met.
The problem here is that one owner might operate several forums under several domains. We are not allowed to have more than one Associates account per person. See where this is also a problem? If one of their staff happens to check in one day and notice one of the forums has mismatching email, then they could pull the plug for that reason also.
Again, I'm hesitant to poke Amazon over their current rule, as they may come to the conclusion that yes, they should include preventing
all Internet forums in their terms and conditions, vs. their current rule regarding posting in Amazon's forums only. And that would get all of us kicked out.
