Vegas has been going scorched earth on STHs who sell a high percentage of games. They won't tell us what the threshold is, but they have been yanking accounts since the Finals ended last June. The Knights felt like they got shafted all year in season 1 & especially in the playoffs for what resales were going for, so they took it out on the STHs who wanted to finance the cost of their season by selling a bunch of games.
They also decided their partnership with StubHub wasn't yielding enough profit, so they ended that affiliation after the Finals with a law suit. For season 2, they started their own secondary market site where they now charge resale fees to buyers between 25 & 40%. Now the team makes money on the initial sales & the resales. And since all tickets are electronic, they are they only game in town if you want to list your seats. They have made it clear than anyone listing tickets for sale on SH, Vivid, FB, or even Craigslist will be subject to having all seats revoked instantly. So for the VGK, I'd say it's 99% about tracking how many seats we sell & the method we use to do so.
