Is it illegal for community owners to post property missing feedback information on public elevators?

The elevator is a part of the community owners * * * and * *, and it is not allowed to engage in any behavior unrelated to its use function. However, because it is * * *, if the owners' meeting or owners' committee agrees, publicity and bulletin boards can also be set up in the elevator.

As for your inaction, it depends on whether the situation reflected by others is true. If it is not true, it can be concluded that the owner provided false information to unspecified others, which caused the social evaluation of your company to decrease and infringed on your reputation. You can sue for damages (if any, you must provide sufficient evidence to prove it) and publicly apologize to eliminate the influence.
