Wouldn't work, by participating in the Amazon Affiliate Program you agree to mandatory arbitration.

http://www.consumerreports.org/cro/shopping/the-arbitration-...

but if they say you copied content that you created yourself that seems slanderous, surely that isn't bound by arbitration clauses.

It's not slander if they just say it to you. They'd have to say in in some kind of public venue.

In these situations (AdSense too), they barely give a reason for your removal from the program. It seems like you almost never have recourse besides trying to raise a fuss on social media, and if you don't have clout, that will almost never amount to anything.

No reason to get a lawyer involved. If Amazon owes you less than $5k then file a small claims case against them.

In some states, the small claims limit goes up to $25K. They closed my account in the past and I took them to small claims for the five figures they owed me and I won.

I know of two other people who also took them to small claims and won as well. (both in states with five figure small claims limits)

They have to show up or summary judgement is issued.
