I am curious to know if units of evil associated with an account reduces when a decision is reversed;
I am not sure if units of evil are removed from IP/ranges when a ban is reversed, or not.
In either case, the effect of a single ban is very small, and it is unusual for bans to get reversed when compared to the total number of bans issued (there are thousands of bans issued for things like spambots). I don't think it would be very common for someone to have to pay a fee in order to register due to a single erroneous ban.
Most units of evil are the result of spambots.
Also, does signature ban or temporary ban affect the evil points?
My understanding is that a unit of evil is applied to the IP/range as of the time the ban is applied. I understand that a signature ban is typically applied in addition to a temp ban that is much longer than the temp ban, and is given as a way to allow someone to continue posting, but not to be able to advertise in their signature.
AFAIK, there are two types of Evil Points, one is associated with your IP address (that used to create the account,) and other for your account.

As for the account points, they remain permanent.
I read the
entire post you quoted, and I think you are reading the information incorrectly. If you create an account, and due to your registration IP address, you need to pay a fee of
x BTC, this amount will remain static, even if a long period of time elapses and no additional accounts in the IP/range are banned.
This could result in someone creating an account one day, being asked to pay a fee of
x BTC, never pay the fee, and months later, create a second account using the same IP address, and not being asked to pay a fee to be allowed the post. The first account would be unable to post until the fee is paid, or is whitelisted.
