# Impersonation via XEP-0297 Stanza Forwarding: | |||
Similar to the MAM impersonation but with a top-level <forward> element. | |||
Clients are supposed to clearly indicate that a message has been forwarded. | |||
Misbehaving clients might instead show the forwarded message as if it came from that person. | |||
There's also zero guarantee that a forwarded message is not in fact a forgery. | |||
