I don't see why, despite elucidation, duality cannot be allowed nor why it is seen as so invidious that there has to be 'A Rule' about it.
We self-regulate, I have seen it happen. Someone will mention, 'there's another t***d about this.'
(or maybe that was GN mole?)
Rules which seek to prevent personal abuse, advertising (not always successful in either case)
) and scams I can understand and agree with - but duplicate subject strands?
<sigh> 
Maybe because old people often repeat themselves, we are seen to need strict regulation?
God forbid we should say something twice.

I've lost count of the times I've started to tell my son something, realised it sounded familiar then seen a smile on his face.
'I've told you this before, haven't I?'
'Yes, Mum.'
Maybe we two need A Rule?
