If it really only was a 3 minute transmission:

- it would not be verified by current peer review processes if detected
on earth;

- in one sense, the communicating lifetime of the human civilisation might
only be 3 minutes, which rather reduces the Drake equation score - of
course this doesn't allow for leakage signals.
