Question about Black Friday

Could anybody please explain in simple terms what was banned by the US government. I am struggling to get my head around the legalities, thanks.

I think this article will help you greatly.

I am aware of the link, but I am looking for the laymans.

Black friday was because pokersites were using alter accounts for transferring funds to us players.. If i was to make a deposit, it would charge my card as a retail purchase for some unknown clothing store in iowa or something. They were not displaying where the money was really going or coming from when we made our cashouts.The government didnt like the cover ups and the sites that were involved were banned from the us
