Hello, as you may have seen, we were getting quite a few bots from this spammer. To stop him, I had turned up our VPN/Proxy detection threshold. Your IP was detected as VPN and had a fraud score of 75, both of which triggered the auto-ban system. I can't tell you what you have done to get a fraud rating as it is beyond my control. I have lowered the threshold a bit and pardoned you. Sorry for the trouble.
