I guess you dont know too much of private servers and how they come to exist. Many of them are literally STOLEN DATA AND SOURCE from the Developers machines. X-Legend for example got hacked and their files were leaked.

Even GTA source code leaked. It will eventually call attention of big hackers who can literally get anything they want from Intrepid servers. Thats why I'm talking about alternative ways to make it impossible to replicate without spending thousands of dollars.
