I just don’t know why you would do that. It’s not competitive, and it’s mostly used to have fun or to make things easier. Just, why?
I hope our blog post from last year can answer some of your questions.
“Modified clients” are a large problem for VRChat in a variety of ways. Malicious modified clients allow users to attack and harass others, causing a huge amount of moderation issues. Even seemingly non-malicious modifications complicate the support and development of VRChat, and make it impossible for VRChat creators to work within the expected, documented bounds of VRChat.
Malicious client modifications are responsible for a massive amount of issues for both our team and our users. We’ve been listening to you cry out for a solution to being harassed, griefed, and constantly crashed, so we’re taking further steps to address one of the roots of the problem.
Our Trust & Safety and User Support teams witness first hand how much damage modified clients do to the platform.
Every month, thousands of users have their accounts stolen, often due to running a modified client that is silently logging their keystrokes as well as other information. These users – often without even realizing it! – run the risk of losing their account, or having their computers become part of a larger botnet.
These networks of modified clients perform malicious actions without informing users – such as reporting back user locations to harassers or stalkers, ripping and archiving avatars, allowing mass harassment of users via automated actions, and even acting as nodes for distributed “zombie” botnets. We’ve directly observed this happening innumerable times, and it alarms us!
Additionally, all modified clients – even ones that aren’t malicious – are a burden for creators. We regularly speak to many that have spent hours (or days) debugging user issues, only to realize that the culprit is a modified client. This frustration ultimately has a chilling effect on VRChat creators, hurting their enthusiasm and preventing them from building awesome things.
This pain extends to VRChat support too – any time we update, we get a massive amount of bug reports that end up just being broken modifications. In addition to burning developer time, this support burden also frustrates less technically-inclined users who didn’t know what they were getting into by installing these modifications.
For the purpose of VRChat, it’s more about the anti-tamper aspect of EAC.
