The point is, every L2 server is based on some sort of project - aCis, Sunrise, etc., etc., but there are some features and fixes that each server owner privided for himself (at least a proper server project owners do that), so this way some ppl can re-create each server features and sell them as "Aaron", "Raina" server files. It's basically bullshit, but some ppl can get tricked by that... Overall - if server owner didn't sell his files or they weren't stolen, there is basically no chance to get those files. Ofc, some dudes can try to re-create server features, but even so, this will be just bullshit. End of story.
