Viber dropped its promise to automatically delete Communities and Channels that go 12 months without activity. That was one of the few spots in these terms where content was guaranteed to be removed on a clock. Without it, public posts in abandoned groups can stay online and stored indefinitely, and the only way they go away is if someone deletes them or reports them. This cuts both ways — Community owners no longer risk losing a quiet group — so the impact is limited, but the automatic deletion safety net is gone.
“Communities and channels that are not active for 12 months will be automatically deleted.”
What you can do — If you posted content in a Viber Community or Channel you no longer use, delete the posts or the group yourself rather than waiting for Viber to clear it out.
