How did this newbie get around the posting restriction?
Maybe someone whitelisted him. I checked: I didn't do it.
As long as it's properly translated I believe it is allowed.
I don't think he hired that many people to do a translation, which means he's (most likely) breaking this rule:
27. Using automated translation tools to post translated content in Local boards is not allowed.
I've reported it as soon as I've seen it on the Spanish section like a couple of hour ago for breaking that rule and spamming all over the boards. He's going to get his posts deleted and probably banned. Just wait and see.
