Online Safety Bill

Could the noble Lord advise us on how he would categorise a site such as Twitter, on which it is estimated that 13% of the page deliveries are to do with pornography? Does it qualify as a pornography site? To me, it is ambiguous. Such a large amount of its financial revenue comes from pages connected with pornography that it seems it has a very big foot in the pornography industry. How would he stop sites gaming definitions to benefit from one schedule or another? Does he think that puts great pressure on the regulator to be constantly moving the goalposts in order to capture who it thinks might be gaming the system, instead of focusing on content definition, which has a 50-year pedigree, is very well defined in law and is an altogether easier status to analyse and be sure about?
