The researchers examined the frequency, types, and success of bets advertised on Twitter by gambling operators versus their affiliates. The researchers examined 10 Twitter accounts that represented five British gambling operators and five affiliates with the highest reach on Twitter. The researchers ran four sets of simulations. The simulations examined returns for the advertised bets. Both operators and affiliates advertised around 140 bets per day. On average, bets from operators and affiliates had decimal odds of 6.0. The affiliates posted each bet three times more than the operators. Only one in five advertised bets won. Bets advertised by the affiliates led to a 12% loss of the original stakes. Operator bets led to a 20% loss. Only 30% of the 10,000 simulations of 14 randomly chosen bets led to a profit. This decreased to 19% when the number of bets included in the simulation increased to 140.
