Check access to the group itself
Availability and history are separate
Find the group through search or a valid invitation. A private group requires an authorised way to join. If administrators restricted access, a bot should not be offered as a way around that restriction.
Ask about history visibility
Avoid leaving as an experiment
Ask an administrator whether earlier history was visible when you joined. Behaviour depends on the group’s settings and state. Do not assume that leaving and rejoining will necessarily reveal previously unavailable messages.
If specific messages were deleted
Visibility settings do not undo deletion
Check an earlier export or ask participants for copies they still have and can share. A setting that changes who can see history does not recreate content that was actually removed from that history.
Proof X does not promise a complete group archive
Do not infer access from launching the bot
This site does not claim that Proof X backs up every group’s entire history. Its described business connection works within permitted chats and received data, not unrestricted access to earlier group messages.
Frequently asked questions
Why can’t I see old messages after rejoining?
History settings and joining conditions may be responsible. Ask an administrator about the group’s configuration.
Can the bot restore a deleted group?
No such Proof X feature is confirmed. A public link or saved messages do not recreate the group itself.
Sources and limitations
Technical guidance is based on documentation. Menu names may differ in your app version. Proof X descriptions are based on project materials; saving coverage depends on data actually received.
