Yes, these Russian girls on the right are online, you can make a search and see other girls who are online now.
You can messageo them and receive replies back in a minute.
I suppose, that you paid on the sites where addresses are sold. All the girls that you can see in the gallery can write and can reply to men. Scammers are usually criminal groups (the center of scammer activity is Kazan (Chuvashia)).
It is unprofitable for this type of sites to check very deeply scammers (as you know, the best pictures and the best profiles scammers have :). We open only about 2 girls from each 3 that register. I have communicated on several Russian dating sites with Russian ladies and met only scammers there. It is not a problem for them to change names, emails addresses, photos, sometimes even the place where they are from.
