I think you mean "ticket touts".
A "punter" can be one of several things. Off the top of my head, it can mean at least the following:
- Someone who punts a boat (propels it by means of a pole). He's a useless rower but a decent punter.
- A gambler. A punter at Pontefract races collected 24 thousand pounds for a 10p investment.
- Someone who's game to give something a go. The next punter stepped up.
