Your domain is probably blacklisted. No amount of proxies and different IPs will help.
And I think you're posting in the wrong section. Try the Social Networking subforum next time:

From my experience Reddit is really cool, they dont ban DOMAINS. What could have happened is that you have been blacklisted from a category.
I wasn't talking about domains being banned. When a domain gets put on a blacklist, it will not either 1) not accumulate karma or 2) even if it accumulates karma will not show up on the 'Whats New' page or the sub-reddit.
I've talked to Alex, Reddit founder about this once when one of my domains was accidentally blacklisted for some reason (thats what he told me). This happens when users mark your domain as spam.
it is one of the only sites where I have seen any random user get frontpage, whereas on Digg only power Diggers hit the frontpage..
