The site is full of fake profiles and bots.
Some profiles are real; you can check this via the video chat.
Many profiles can also be found on other dating sites (findherbride, natashaclub).
If you write to the same girls there, they will even know who you are.
The opposite is also true.
Women are probably paid, the man should regularly open photos and videos. If you reach the required time to exchange contact details, the girls prefer to continue writing on the website.
Try it too - or not. It will save you a lot of money.
