You clearly don't have a clue what you are on about, Mr.pseudo-Russian. There have been numerous accounts of men using these dating introduction services going to meet these women in their homelands and being drugged, robbed, etc.
Enough of it was happening that there were news specials being made about it happening to American men seeking Eastern European women....
and almost every guy I saw on them reminded me of Woody Allen - not that any of them were actually jews, but their slight physical builds and mannerisms reminded me of him.
A lot of the men that use these services are fairly wealthy, very timid when it comes to talking to women, and generally their social and interpersonal skills keep them from being able to meet the women that they would like to meet.
Even the most sincere ones I noticed language barriers popping up.
