My recommended Server is Shiva, (mine obviously). It's an EU server, which does mean that there are quite a few Dutch speaking people, but there is plenty of English players as well. I'm from NA, and joined Shiva from a recommendation I received when I bought the game. I can confirm that the community is both active and friendly on it, and if you do join you're welcome either my small FC, or I know a couple of good other ones that I can recommend.....

EDIT: I will also add that the RMT spam is pretty docile compared to other servers. We get maybe one or two friend requests a day on average, hardly every any tells or shouts, and only recently have I seen any players at all using /say at the aetherytes......
