Have you actually looked up rowanwater or the other site? They’re obviously not designated traveller sites.Some of them live in designated sites, they don't just always 'pitch up'. There's been one near me for over 40 years, when it was raided they found everything in-between the local gates to the cemetery that had been stolen, to modern slaves, some of whom had been taken in & kept for 2 decades nearly & forced to work. It happens.
