I skimmed the official forums for a moment and found a few threads which might be useful information:

Here some overview information on our new Server. It seems to be written by a spaniard and I dunno how accurate everything is, some things sound pretty much like opinion-based.

A thread called "new transfers, things you need to know". The initial post was made by a pirate.

Some pirate skill builds/templates, posted by the same guy.
In short, it seems the Rack (as they call it) claims to be the server with the best pvp players or the highest challenge for that. Another claim is that the pirates haven't really been that organized so far. The server is on round 2, the Spaniards had won round 1.
I wonder if those claims are all true and if we really will have a harder time being ganked and stuff. Ganking seems to be common among the other people on the Rack, so expect to be 6vs1 ganked if you head into any red zone alone.
