Playing on BBO.
I open a weak NT LHO doubles.
We are playing some flavour of Halmic, and partner bids 2H which should show 4/4+ in majors.
Though of course I see only the bid.
RHO doubles and self alerts as 'Hearts'.
I now have information that suggests partner may have forgotten the system, or may have missed the first double.
However reading Law 16 I can't find anything that categorizes this information - from an opponent - as 'unauthorised.'
I am sure there must be lots of situations like this when screens/self-alerts are in use.
Is there any guidance?

Information that comes from your opponent is authorised, though you use it at your own risk. It might just be his way of saying that he has a penalty double of hearts.
