Chris Wilson, one of the creators and the game director of Path of Exile, spent part of a recent video on his personal YouTube channel walking through years of efforts to counteract data miners who probe game files. He opened with a self-deprecating quip that his current gray hair is a direct result of dealing with enthusiasts who dig into game code, then moved on to concrete steps studios can take to limit the fallout.
Wilson framed the problem this way: data mining is essentially unavoidable, and the files uncovered by miners usually lack the context needed to interpret them correctly, which leads players to draw incorrect conclusions about developers' plans. To reduce the amount of misleading material available, he recommended automated build-cleaning processes that strip a release of any assets not required for the running version of the game. He emphasized leaving only files relevant to the current game version so that remnants of cut content or hints about future updates are not accidentally exposed.
Some developers, including me in the past, added fake files to the game code so players wouldn’t know what to believe. But it’s quite a wasteful process. Although it’s great for trolling.
Wilson acknowledged the trade-offs of that tactic: creating fake task lists or bogus assets consumes development time and can be inefficient, but a well-timed joke can spread quickly through the community and sometimes blunt the impact of persistent leakers who publish unverified findings.
Encryption was another tool Wilson discussed, with a clear limitation: it helps only up to the point of release. Once a game ships, its files must be decrypted for it to run on players’ devices, which opens the same vectors to miners. He noted that fully stopping data mining is essentially impossible and suggested the difficulty multiplies for large franchises — citing series like Diablo as an example where scale compounds the challenge.
Ultimately, Wilson said the most reliable approach is cultural rather than technical: encourage the community to treat mined code with skepticism. Slipping in a humorous red herring can be a bonus, but he did not indicate whether developers working on Path of Exile 2 currently use these tactics.
