Why did one of the world's best-known porn provider platforms, OnlyFans, decide to ban porn? The controversial site has become a global phenomenon over the last five years, but its decision to outlaw adult content got everyone talking. It appeared to bow to pressure from financial services companies and anti-porn groups. Then it changed its mind. We look at the pressures the company is under and also at the business logic of internet porn. We speak to content creators Jessica Starling and Alana Evans, President of APAG; Mike Stabile, Director of Public Affairs at the Free Speech Coalition and Alexander Konrad from Forbes. BBC reporter Noel Titherage talks us through his investigation of the site.
