Could a payment handle be reassigned or changed?¶

Yes. A public handle, linked email or phone can change hands, while the underlying account may remain stable - or the same visible name may belong to a different account later.

Current profile is not historical proof¶

Users can rename handles, providers can release inactive values, and contact identifiers can be recycled. A later view therefore cannot establish who controlled the identifier during an earlier transaction.

Anchor history to stable records¶

Preserve event-time screenshots, messages and transaction IDs. Obtain handle history, change times, internal user IDs and contact linkage, then compare funding, endpoints and logins.

A post-event change may be relevant but is not automatically concealment. Where provider history is unavailable, state the limit and do not attribute old activity from the current profile alone.
