It is a bait and switch agency so it is highly likely the escort who turns up will not be the woman in the pics. That agency, under many different names (Ashley, Shush etc) and associated websites, has been around for 5+ years now, still using tons of pics that they stole either from escorts who worked for genuine agencies/parlours in the Manchester region, or simply from the web. To my knowledge, they have yet to have a good report on any of the NW forums, though it is possible that among the many stolen pics, there might be some of women that actually work for them.
To give you an example, the pics of Alizah, Gemma and Chelsea were taken in TWL parlour in Bury which closed a few years ago. Angel's pics were taken by Northern Babes agency in 2010 or 2011.
As a general rule of thumb, the genuine agencies use pics that were clearly taken in the same studio so you see the same background shots again and again. Genuine agencies include Manchester Elite, Angel Companions, Cheshire Companions, Mckenzies, Bond Girls and Secrets (some of these have additional websites under different names which confuses the issue). I've probably forgotten some others. Not sure what the situation is with Northern Babes these days, probably better to avoid given the uncertainty.
I would only recommend risking an agency encounter if you can find an enthusiastic report of that particular agency escort on a forum. Different if you are regular of one agency, then you'll have a better sense of typical services on offer and how accurate the pics are.
