I noticed it first a few years back when we had a neat batch of genuine students in Edinburgh. They were all young, intelligent, well-presented and well-spoken. Quite a few had the 'only see you if you have feedback' thing. It doesn't annoy me as I keep some feedback just for that purpose, but I can well imagine if someone lives in London they'd think why bother when there's so many. Of course, it can be someone who's a had a bad experience but I think more the part timers, at least up here. Of course, if she's a totally stuck up cunt it'll often be apparent from other things on her profile.
I'm more concerned with whether she answers the phone/email promptly and follows through with a clear booking. The no feedback thing can be totally different and personally I suspect it's sometimes the ones that speak zilch English and can't even use google translate, so they state no online bookings, phone only. But Serge is gettng wise to the facts that zero feedbacks puts people off so he just does fake feedbacks for them from different ISPs.
Now if an
English-speaking girl has a profile and she's been around for more than a few weeks and still has no feedback then I think that looks dodgy.
The question from punters about how to get feedback comes up often: but this is punting, not iMac. If you have no feedback then you have to skip the ones that expect it until you get some. There's no harm saying at the of a punt that went reasonably well A) if you booked online: "I don't usually give gushy feedback, but it's nice to be nice and exchange a few words of feedback with each other..." (Pause and look at her till she nods and says ok as she pushes you out before her next captain clegg clocks in.) Letting her leave you feedback first is the safest of course but there's no rule. B) If you didn't book online: "It would be nice to leave you some nice feedback, but I'll need to put a fake booking in so the system will let me. Shall I do that and we can exchange a few words of thank?" (emphasising the 'exchange' bit of course but making it sound reasonably casual). If she doesn't understand teh ruse you have to explain it.
To be honest it's fucking two faced and I'd hate doing it but if you really have to ... All I'd say is don't overdo it as you'll look a right prat. Just "had a nice time xx" is fine and probably more than she deserves anyway. She'll have an auto cut-and-paste, nice gentleman, can't wait to see him again, treat him right ladies, all that rubbish. But if you just punt Romas you may be up against it. There are other more devious ways of doing it but if you need to ask you're probably better not knowing.
I recall JRC (another Londoner) saying he'd never book someone without a phone and a face picture. Well before the Roma invasion, that would have cut out 99% of the prossis in Edinburgh. Adjust your choosines to the area where you punt. She's only a whore ffs, so don't get all obsessed. Save the dreamy-eyed crap (if that's your thing) for when you have a booking and she is actually doing the gfe.
Hope that helps. Most of it is probably on the ukp wiki tips anyway.
