It's an indication that your IP address is once reported for evil and you have to pay a little evil fee to bypass this restriction on your IP, alternatively, you can get a member to vouch for you, or use the recommended link to get whitelisted, also be informed that not every country has this proxy restriction, except your country fall under the regions that were being affected.
What you mean by someone's IP being reported for evil. I don't think it works that way, no one reports any IP, they accumulate the scores themselves.
As explained by Welsh by his illustration of owning a car previously owned by another person. The Op might be paying for an evil he did not commit.
For instance, Nigerians use a kind of shared IP. I haven't scammed anyone, I haven't been banned and I don't think I should have an evil IP, but while registering, I encountered an evil fee and a few accounts I have introduced to the forum all had the evil fee.
But I'm curious, OP managed to register a second account, maybe he did that with a VPN or Tor.
