Did you open a new account? If yes, then it was probably blocked due to some level of evil associated with the IP. In the error message there is a payment process which lifts the ban on posting. I'm guessing the units of evil associated with your area was lower when you registered this account or you changed location.

When you register, the IP that you used when you submitted the registration form is used to calculate your evilness. The more frequently this IP or its neighbors were banned, the more evil is associated with your account. The amount of evil associated with an IP decays slowly over time, but the amount of evil associated with an account does not. You must pay or be manually whitelisted to enable posting on one of these "banned" accounts.
Here are some stats:
Currently each unit of evil requires a payment of 4023 satoshi. You only need to pay something if you have 1 or more, though.

I've had an account for a while, and it's this one. It's the only one I have.
I'll try posting again. My post did possibly contain a keyword that was not allowed.
