There are regular posts on this site about the Romanian invasion, but I've not seen one that addresses these two issues.
I keep a vague eye on Vlad the Impaler's girls, for the purpose of scholarly investigation. We all have our theories about how the operation works, but here's mine.
First – incredible though this may seem – I think that most of the girls may be controlled by a single organisation. One thing I've noticed is that their Enjoys Lists are usually identical: anal is (supposedly) on offer; rimming is "receiving" only; spanking is "giving" only. I can't believe that in the villages of Transylvania every girl does exactly the same stuff in bed. So this is Vlad and his English colleague's standard list. The same Vlad in each case. I think.
Secondly, I'm puzzled as to why the girls keep being carted all over the country. If I was Vlad – nice work if you can get it – I'd settle each girl in one of my mini-brothels in a particular town, and let her bed in and indeed try to develop a regular clientele.
(One possible explanation is that the majority of Transylvanians give such poor service that Vlad needs constantly to shift them to new places where the – smallish – pool of punters who use Romanians haven't yet cottoned on to the fact that a given girl is a waste of space.)
