I agree with you. There never has been and never will be profanity on the Internet. No dirty pictures either. Actually, maybe you meant "if you can describe yourself without using profanity", which sounds more like a problem for the Internet I know.
Anyway, I can't figure out what Amazon is on about. Maybe "oderanc" is a vile insult in Icelandic, and their screening program smugly recognized your feeble attempt to disguise it? Did you try any variations, or JavaRanch.com?
