the second of the possibility to count this fee when buying copper membership. I am not sure about this point but I believe I saw it somewhere in the past.
Anything you pay towards your evil fee is subtracted from the price of a copper membership, and the evil fee is capped at the same price as a copper membership.
Here are the relevant posts from theymos:
If you paid an "evil IP" registration fee, then whatever you paid (in BTC terms) is subtracted from the upgrade fee.
OK, I reduced the maximum to the same price as copper membership, since it doesn't really make sense for copper membership to be cheaper when it includes whitelisting.
