What is Proxyban?
When a user is proxybanned, it means their IP has some level of evil associated with it from previous use and they need to pay a stipulated fee to enable posting.

Evil IP is a deterrent to prevent banned users from registering new accounts on the forum;

When you register, the IP that you used when you submitted the registration form is used to calculate your evilness. The more frequently this IP or its neighbors were banned, the more evil is associated with your account. The amount of evil associated with an IP decays slowly over time, but the amount of evil associated with an account does not. You must pay or be manually whitelisted to enable posting on one of these "banned" accounts.

Currently each unit of evil requires a payment of 4023 satoshi. You only need to pay something if you have 1 or more, though.

This feature however sometimes affects honest new users who may be discouraged from registering on the forum. In this case staffs have the ability to whitelist new users and now some members have been giving that ability as well;

Only abused IP ranges have to pay a fee. The fee is an anti-abuse measure, and it is not meant to be (and isn't) much of a source of revenue.

If any very-veteran members want to volunteer, I can give you the ability to whitelist users. (All Staff can already whitelist users, as well.) Perhaps then someone could create a topic like "List of email addresses for people who can whitelist you for free", which I could link-to on the evil fee page. However, these IPs have evil for a reason. If it was sufficient for them to just solve a captcha or something, I'd have them do that. Before whitelisting someone, you have to do something to be pretty sure that they're not evading a ban and just going to get banned again. You may get the impression from complaints on the forum that everyone hits the fee and it's never warranted, but this is selection bias: the fee is more rare, and the vast majority of accounts that hit it should not be whitelisted.

How do you go about it?
If you're a brand new user to the forum with no previously bannd accounts;
