This has NOTHING to do with your country, its cars, your pictures, etc.
The only problem is your behaviour! With the amount of insults and aggressive comments we can't accept that on the site. Other people with such behaviour were banned in a few hours or a few days. I waited a few months before that, and you were warned previously. This is not a definitive ban, it was just to give a more severe warning...

This is an international site. If there are problems between some Brazilian and Argentinean people, this has nothing to do with the site so it should not be used as argument there, unless it happens on the site: we only care of what happens between people on the site to keep it "clean" and with polite exchanges.
