Been punting, on and off, since 1986. As mentioned earlier on, the advent of the internet has, to a great extent, reduced the risk of a bad punt massively.
No more phoning a number advertised in the Sunday Sport/Exchange & Mart, cards in phone boxes and asking what services were on offer.
Because of the advent of AW, you by and large get some idea of how the WG is going to look, as opposed to being told that "the lady is an attractive busty blonde in her 20s" and trusting to luck that that was true.
Then again, technology works both ways, and e-mails/AW and mobile phones make it a lot easier for WGs to air grievances (ok if genuine) about punters, which will include when WGs get vindictive/weird/spiteful. There's a certain lack of anonymity that's come with the internet.
Certainly I think the mystique, or need to act far more furtively has gone out of punting. Don't know if that's a good or bad thing. Maybe the thrill/excitement has been dulled? Also, I think pre-review sites such as this you could maybe kid yourself that you were one of a select band, and that your favourite/regular girl wasn't being banged by all and sundry.
I certainly think that escorting is now seen as a lifestyle choice/good career option - and good luck to those that choose it.
Definite negatives are the rise of Sergei and trafficking.
