I just read something a little scary. Here's the story: I got a domain and hosting and am using a wordpress platform to blog. It is "mydomain.com" and not "mydomain.wordpress.com" scenario. Now, I just read something about how to do affiliate marketing despite WordPress. Do I have to worry about this or is this only an issue for those being hosted for free on the wordpress server with a wordpress domain?
Have not really understood your question. But if I am correct to guess your question, You need not worry about affiliate marketing with your own domain or free blog, as long you can get traffic and have a good landing page or review page.
