Rovo
It is very normal for several agencies to list the same woman.
It is the same as you being on several sites. This venture is probably not for you.
ROVO........it is same girl but realize the names are all a form of one name....Jelena, Alona, Elena sort of
like nicknames as is Elizabeth, Liz, Beth, Liza
Good Luck
ROVO, some women change there profiles often, its like when you first join a site you get more mail then usual, new profiles always get more interest then old, she just trying to get seen, possibly you may find she is really looking for someone.
Check the other profiles Rovo to make sure the weight, height, date of birth, city are the same or consistent.
Elena can have variants on the name. Some spell it Yelena, Lena etc.
I wrote to a few "Elena's" in my time, its a common Russian girls name.
Here's something funny.
The former Miss Krivoy Rog girl I used to write too but dropped had a profile on one dating site where she became 2 inches ( 5 cm ) shorter and 7 kilograms ( 16 pounds ) lighter than her other profiles on other sites but all used the same pictures of her.
When you get inconsistencies like that in profiles between sites, its when you should get suspicious and wonder about whats really genuine!
Other things to look for between sites, changes in her age and when if she has kids it appears or disappears off the profile but all the photos are the same...I come acroos girls profiles like that many times ( not here but other sites ).
You learn a lot while fishing around many dating sites over a few years.
Some profiles are so poorly done or so obvious its "a scammer", you can figure it out on the first look.
Google both her names and see what comes up.
Rovo, sorry to tell you this, but I agree with the others ... it is shoking at ther first time, but you must give yourself some time, as well as for the others, as long as they don't ask you money ... then you don't need to be afraid of anything ...
if you are not patient ... then forget this kind of services
