That was their policy since 1998/1999. The company was started by 2 Russian born MIT Students in Boston sometime in the mid-1990’s.
They have (had?) Harrod’s as their client.
The last thing the want to do is
(1) Jeapordize their relationship with Harrods by taking US wagers
(2) Jeapordize themselves legally as they are located in Boston.
Like I said, they are very unlikely to play games with anyone in this business.
