You do find some Moldovan girls in German clubs, but as stated it's harder for them to get visas, many go to Cyprus or Dubai to work.
As for Moldova itself, the country is split in two, with a small breakaway territory of Transdnistra who are Russian speakers loyal to Moscow.
I did do some research a while ago on Moldova on ISG, there isn't a punting industry as such, you just meet girls in the street or in clubs and bars.
