Downloading WOTLK in Germany?

Hello guys,

I have played WOTLK before when I lived in a country where downloading from torrents it not illegal. But now I am living in Germany, and downloading here is very illegal and I could get fined for downloading from illegal sources.
But throughout my gaming career I have encountered many players from Germany and countries with similar laws, so my question is how can I download WOTLK now and not get fined? Downloading from legal sources is impossible because WOTLK is outdated by Blizzard?

Uhm, VPN perhaps? A decent one that's not free just to be safe.
