Whether posting once in a day or 15 has nothing to do with whether your account(Fan page) will be banned or not.
The thing is, if you are planning to post affiliate hop links from clickabank (CLocked or non -clocked or anything of that sort) on your fan page and sending visitors directly to the vendor's site.. That's a WRONG approach.
Clickbank does not work that way..these products are much of a pre-selling.. You must pre-sell the product yourself. This can be done in many ways..either use a Review article (Review not a BS selling post trying to list features of the product..instead list how this product help you and to know more abuot the features where they can go (The hopelink). Once you have the article ,post that on the fan page...Much more effective and proven way to clickbank.
Or you can use product comparison (Review of 3-4 products) of your niche on a domain (Use any review theme available ) and post the links on facebook page...
Does that clear your question?
