how come when I try to vote, it says "ACCESS DENIED: Botnet Node"?
Because you are a botnet node. Your router or computer has been taken over by someone else, and they are using your computer as a node on their botnet.
To be more specific, your IP address is 69.196.73.195, you are running an open HTTP proxy on port 80, and you are listed on DroneBL.
Edit: According to the googles, you're listed on several other open proxy lists too, you've been used to attack several domains, and you've been used as a spam relay.
People have used your IP to spam and vandalize several wiki sites, and it's been involved in hosting content for pornography.
Edit Edit: wait, this isn't your IP at all! You're using an open proxy on purpose! LOL CHEATER! Now I wish I'd been less nice! I'll be calling that server admin Monday, so whore it up while it lasts.
Conga Rats, you are the cancer killing the internet.
