Here is a quote from Michael from Casino City and GPWA, who sued the government about this stuff:

Thus the Louisiana statutes could not be used to go after portal webmasters. Personally, I also think there isn’t really any risks for affiliate reps unless they are also part of the upper management of a sportsbook site.Michael
