I'm an affiliate manager, so who I will be promoting on my sites, doesn't quite pertain... but I will be promoting the USC Trojans to anyone who will listen to me once the NCAA college football season starts!
BetUs is as shady as it gets without being an outright scam (outright is keyword in this sentense too as they're very much a scam).
Sportsbook is on the shadier side but imo Sportsbook's stil a C+ . BetUS is D.
Since the 90's its always been true that the shadier a sportbook is the better affiliate managers, commissions, customer support and bonuses they offer. Its too bad money losens standards so easily because BetUS and similiar companies would of never made it witout sites and marketers for sale to aid in their scams. These companies anialated the opportunties for honest affiliates to making a killing in sports betting, still some money there but not much for American sports while working with just the top programs.
