I have been quite lucky on Vivastreet, key is, as with most things, if it seems too good to be true, it usually is. I find vivastreet more user friendly on a mobile. I tend to ask if the photo is real when I call, they always say yes but then you won’t get a reply if you ask for their location. In leeds you will find the girls in Holbeck and Beeston are usually bait and switch. Avoid any ones with pictures not showing face or which is clearly photo shopped “professional” looking to save yourself time
