Many people buy disposable domains and make money until the search engine bans them. By then they have another disposable domain and start over. So affiliates with long term domains can't compete with the spam, they promote another merchant who doesn't allow it. The problem with the se spammers is that they cause the search engines to keep changing their algo. Makes it hard for even properly optimized sites to rank these days. I say kick the major spammers, they are bad for everyones business.
