Yes, but those are rarely a thing for most live service games. Unless someone is working on a reimplementation of the entire server side, there's no point in offering or downloading pirate copies.

There is - albeit a dwindling - community that does reimplement entire backends for mmo games. Look up the ragezone forums. I grew up around Mu Online private servers. And I'm sure in time a private server for HD 2 will appear if arrowhead don't release one themselves :)
