Some of what you all are describing sounds like nearly the same m/o for "heartdetectives" that others have already experienced as being a scam. They've shared on another thread active here right now.
LOVE that part about how they disclaim the occasional fictional emailings. Oy, goodness. Purely,
PURELY protecting their you-know-whats because of the lawsuits that have been placed against certain other established sites re similar things alledgedly going on within.
BTW, I've been the route where I've created a second profile on one site and been "hit up" by the same people nearly as soon it goes live, but they don't appear to be from Russia. Actually,

, the same fellas hit me up on two sites nearly on the same day when I had decided to give online dating another shot a few years back.
Feels like they're just lookin' for a good time and trying to be the first in line for the new "meat" on the market. 'Sides, figure it probably hasn't been occurring quite the same for girls (gathering most of this is happening for the guys).
