Ban List False Positive

I’m trying to register on Wil Wheaton dot Net to be able to make replies and every time I try to register it gives me a false positive that I’m on the banned list. Is there any way I can get this fixed? Is it something that will have to be fixed on his end or is it something that can be fixed in the SABRE database? I would like to be able to make comments on his blog. I am using a Verizon WiFi Hotspot. Let me know if you need any other information.
