Being 100% honest, I'd give all three a miss. Reasons:
No.1. Member since June 2013, no feeback, seems part of a group also with none or little feedback. Could be larger than size 12. Doesnt strike me as a regular WG.
No.2. She's Romanian, they are generally unreliable, tend to be pimped and usually fail to offer the advertised services. Plus, she's not in the UK, accessing from Romania, and last log on was Jan 24. Her last feedback was August 2013, so clearly not a regular WG.
No.3. Been on Adultwork since October 2012, no feedback in 18 months. Last login nearly a month ago.
There's better in the area, have a search for Wellingborough, there's a couple of cuties there who are good value and are genuine. Personally, I'd never visit a lady with zero feedback, or feedback from other punter who only have small single figure feedback of their own.
