Who made the open mic a slam?

The artists say the host.
The hosts say the audience.
The audience says the promoters.
The promoters say the venue.

But the venue just wants to be paid.
The promoters just want to fill the room.
The audience just wants to be entertained.
The host just wants to have order.
The artists just want to be heard.
And nobody wants to take the blame.

There were no judges to be found.
