Yep, 'hunners' of them at the moment and nearly all Vivastreet.
Whilst I'd never pay upfront regardless, the recent ones wait until you're already en route or parked nearby so that the 'little brain' is starting to lead. I imagine some people are being caught out by this, only last month one told me in a text message what colour shirt I was wearing and confirmed it was me, to only then send me two messages by SMS. One with their bank details and immediately followed by, 'Ok send deposit bby to my bank, just £25 for my safety. XX'.
IMHO there's little point in sharing the 'fake' names of the workers because they will change, you can usually spot the style of the writing anyway over multiple profiles and always too good to be true. Like she's eighteen with a great body and does OWO, French Kissing or other less common services at a tenner below the typical rate - if it's too good to be true stick your dick back in your pants. However, the pictures are recycled often so sharing those could be helpful, as is raising awareness.
