Before understanding the "patched" part of the keyword, we must understand the ban system. Minichat is not an anonymous free-for-all. Unlike Omegle (which shut down in 2023 due to safety concerns), Minichat requires a Google, Facebook, or Apple ID to log in. This creates a persistent identity.
The era of the old Minichat is over. When a platform issues a "ban patch," they aren't trying to inconvenience you; they are changing the architecture of the house. You can try to pick the lock, but the rooms inside aren't the same anymore.
