They are scams. Despite the plethora of EI women in Vancouver, it’s not a profession they go into, and if they do they are very private and secretive about it. The EI community is massive here, but the girls worry about parents, friends and their thousands of cousins finding out and “outing” them. It’s still a very old school culture.
Don’t waste tour time with those ads, unless there are reliable reviews on the ladies.
