Use app activity to scale the reserved bloc of tickets. Dedicated fans still get to attend shows. The goal isn't to maximize ticket revenue, but to fill venues with a quorum of fans and sell them status-signaling merch.
You can realistically expect your real fans to buy one tee per tour. Farmer accounts will likely show maximum sweepstakes entry activity and no game-play activity until winning a lottery, then will refuse all the merch upsells and never be active again. You can just dump those user ids into the "ignore" bucket and rescale your reserved bloc so that there are still enough seats for the real fans.
In any case, why would anyone buy a transferred fan club burner phone instead of a transferable dollar-priced ticket from a scalper? Why crack the proof-of-fandom test for a single artist, when you could break the CAPTCHA for all of Ticketmaster? The hypothetical attack you imagined requires greater effort and produces less profit than if you were just a regular ticket scalper.
