As I have been looking (more accurately, trying to look) at some Bitcoin related online gambling programs to promote, I have been discovering that ones which do not accept US players also block you from visiting from the US.
I have never seen that before with "normal" casino and betting sites even if they do not accept US players. This is a problem for someone looking to promote as a US affiliate for non-US traffic, however. Is this now a trend for all types, or just a quirk among the Bitcoin-only type sites?
