We'll try to help you. The number of Russian-Western marriages have been increasing for the last few years. There are several matchmaker agencies in St. Petersburg providing you with this kind of services.
Some agencies publish photos of women,whom they maybe never have seen in person ,sell non-existen addresses and get money from men for a such fabricated information.
So you correspond with a woman for a while by means of such agency and when you decide to meet with her in any European city (not in Russia) she will ask you to send her money for this travel. You'll never see girl and your money.
Such things can happen to you.
