There are other directories that also request you to pose in your same lingerie in order to be verified. It sounds weird at first but I can see how it may be effective.
I think BBC are just trying to get viewers attention by making un-informative programmes full of conjecture that they know people will love to have an opinion about.
They clearly saw what a huge thing it was in America when backpage and craigslist got pulled down because of fosta/sesta and are trying to reflect a smaller scale mirror image version of events in the UK. They seem to try and do this with other politicised issues too.
I used to follow BBC news and enjoy their documentaries before becoming a sex worker, but now I don't bother really, because the twisted load of compost they churn out about our industry makes me doubt the value and integrity of their reporting on other topics.
Like someone else said, if nobody from within the sex work space has been consulted for this programme, just police, academics, and journalists, they are not trying to explore or improve issues that may be present within the sex industry, they are simply trying to make 'entertaining' shows at taxpayers' expense. Clickbait TV.
