Just figured out something...
My IP in mkpc is banned... again. I have a pro tip to be safe for your IP to be banned, and you're not on your account, create a quick mode circuit and see if it says "Share circuit."
I highly blame one guy with too many names... "Francisco Ming," "RabootCo," (not me btw) "Sire€€€€€€€€€€€€," and "«Sire»."
