Wise up, BT

As BT is forever crowing about its technology, surely it can prevent nuisance calls by 
interrogating withheld numbers before passing the call on or not, as those who withhold a number are up to no good by definition.

Now coming at night and early morning, they are alarming for anyone with a family member in hospital, for 
example.

But perhaps BT’s failure to do something is because they make money from these calls.

Would a BT representative please grace your pages with an answer to this problem.
