- basket size limited to IIRC a maximum of five tickets for the same concert,
- name of the buyer is linked to (idk, maybe even printed on) the tickets AND
- the named buyer would have to be there with the group to enter the venue.
I think this would probably be pretty effective in countering that bottom-feeding scum called scalper.
This arrangement works great: the reputation hit is very successfully outsourced to what you call “bottom feeding scum”. The band benefits from higher profit than they would otherwise be able to get if they tried to sell all their tickets at the publicly advertised price, which quite apparently is below the market clearing price. Ticket availability is increased: instead of having to fight to book the tickets in 8 seconds after the registration is opened, everyone can buy tickets at their leisure, simply paying more for convenience when they buy from scalpers.
Let me ask you this: for the band you are talking about, despite all the measures you describe, you still could buy tickets on StubHub, no?
