I'm definitely not from Russia, my schedule is totally broken now (which is bad for earnings). I would say I have 35% of Russian members, 35 of European, and the remaining from the rest of the world (mostly australia, north america, some indians and israeli too)
I'm surprised that there is so few users from north and east Asia. I think that I had only one regular from China on CB and I saw several times a Japanese guy on Flirt. That's a pity because I speak Korean, but I never saw any Korean member on any site. I wonder where do they go, I though about trying Sakura Live, but it seems more Japan oriented.
I wouldn't say that there is a huge difference between users in different part of the world. However I work with an operator, so my experience may be modified by that.
I've noticed that some kinks and fetishes are very region specific.
-I got regularly raceplay RP (interracial bdsm) with users from US. I started to refuse them as the borderline racist side is a bit too much for me. Funny enough all are claiming to be black, but never accept any C2C.
-I had a surge of homewrecker/humiliate my wife/gf RP from Europe. I wonder if it's a lockdown secondary effect.
-The whole daddy thing also seems to be mostly European (and American to a lesser extent) never get any outside this regions
-I have the feeling that the % of bdsm lovers is higher among my Russian members, through that may be because of my voice possibilities with them.
On the bad side, my most disagreeable experiences were with members from Turkey. i have nothing about turkish people overall, but on camsites they are over represented by the most insistent beggars i ever saw. I ended by blocking Turkey on most on my sites. Through I'm regretting it a bit - Seing a guy going from "I'm a very rich men, get naked and if I like you I'll come to spouse you and you'll live as a queen for all your life" to "It's my birthday I am alone and crying, I have even no money for buying a cake, pliiiiz show me tits for free" in 5 minutes was sometimes priceless.
