... is it confirmed?
No, it is not confirmed.
The first time I registered in this forum, I immediately got a proxy ban. Then I tried to register at another place (computer rental) I got a proxy ban too.
So when "IP address" is included in the blacklist
(I use that site for check my IP), my conclusion is that the registered new account will also get a proxy ban too.
I doubt that list shows the proxy ban list used here. DNSBL is used to combat email spam and not directly related to evil points.[1] Probably the same IP address that you used to register was used by spammer/bot to send spam emails, and then a member using that IP address was banned or his neighboring IP address was banned, thus they have evil points.
Well, only theymos can answer.
