My guess is that if you have sent them a message and they think you are not abusing the faucet they will whitelist your IP, just as someone reported earlier.
Problem is, whitelisting an IP is pretty much "bullshit" on most common end user dsl/fiber and mobile connections, since they're dynamic. For that reason I don't even know if the story regarding the guy who's been magically IP whitelisted with a contact message has to be taken seriously. Also the same guy upon changing IP by rebooting his mobile device or his home router may be taken back at halved prize with a different IP.
With this matter what it counts is the account (user id) more than the IP.
It's not my issue, yet, becasue I'm not halved, but maybe most of my referrals are, who knows, and I'm paying the consequences too by gaining less from them, I should take a look maybe at the reports but I don't have the time and the will to do so right now.
I think it means the account is whitelisted so that the IP doesn't affect its status.
