Umm... Chips.gg is the casino with an old case where [ex] internal team got enough of the owner's behavior and decided to be a whistleblower, providing screenshots of their internal chat, of which they unilaterally [not asked by the provider] lock the player's account after a huge win, in hope the player will drain their winnings, and cheered up when it finally did?

That questionable things [and even more questionable deflection they gave as their defense] aside, and strictly speaking about hiring US-based streamers to promote their site, it probably brushed and matched a discussion with a representative of casino [not chips.gg] about one lifetime ago when I asked them about forbidden territory and residency.

They told me that a lot of streamers take a short trip to neighboring country that's not restricted [lets say, US citizen take a trip to Mexico] to make their content, and that's acceptable. So maybe that's what BossManJack do?
