Region lock on steam gifts?

Where I can find which languages are available for other regions?

Also need to watch out for censored versions of games. For example, it would be very unfair of me to gift Left 4 Dead 2 to someone, being that I'm from Australia, and the game is heavily censored here. Once the Aussie version of the game is in your account, you can not replace with the uncensored version. Germany also has their own censored version of some games I believe. It would be very handy if Steamgifts could make people aware of this somehow, maybe by requiring gifters to state which region the game is from, or something along those lines.

That does not happen. The gifter must be able to buy it, it can be redeemed by anyone.
Only Keys might refuse to work.

I can confirm that games unavailable in Australia do work for me when gifted from the US. I have a few of them (MLB 2K10 for example), even an uncensored version of Left 4 Dead 2 can be gifted, despite a censored version being available here.

However I have seen on some of those dodgy "cd key" sites, Russian copies of games being sold as a "VPN" version. I assume this means you need to use a Russian ip address to either activate or play it? I'm not sure - I avoid those cd key places.
