Wat? I've bought in .com, .ca, .co.uk, .fr and .es with (both) France and Spain based credit cards with no problems whatsoever.
PhantomLobe, you were hellbanned* for making a comment that didn't fit the the community guidelines:
http://ycombinator.com/newsguidelines.html
Looking at your comment history, you don't seem to be a spammer or a troll, I think it is more that your second comment didn't fit the guidelines and because you didn't have enough karma your account went under water, never to be seen again.
I don't know if it was by a mod, or by a robot, but to keep commenting with our PhantomLobe account is an effort in futility and a waste of your time.
I recommend that you review the guidelines doc above and avoid making comments that may be seen as not adding to the discussion. Also, start spelling words correctly. Wot is not a word and won't win you friends here.
On a related note: I wish HN would would stop hellbanning users for making comments that are not constructive. That's what downvotes are for! I have been seeing far too many people wasting so much time because they don't know they are hellbanned. Hellbanning should be reserved to obvious trolls and spammers, not people getting used to the standards of these discussions.
