You must follow all policies that have been put in place by ebay. If you do not follow them, you are at a risk of losing your basic membership, let alone becoming a power seller.
There is a requirement of minimum 98% positive feedback in the last 12 months. In case it is lower than this percentage, the power seller status cannot be attained. If you are already a power seller and your feedback goes below this percentage, the status can be lost.
