I appreciate the desire and the passion behind the thread, but how can non-voting fans cause a board to resign?
Wests Ashfield own the Wests Tigers and supply 100% of board members themselves. Ticketed Members (AKA "customers") don't have a say in the makeup of the Tigers board. Therefore Ticketed Members cannot mount a case to force board members off.
In many ways it would be like consumers trying to affect changes to the board of Mars Inc, which is a privately-owned company, because they don't like the new Mars Bars. You can complain all you like, stop buying Mars Bars, but the Mars family own the whole show, box and dice, so you can't force them to give up their control just because you don't like what their company is producing.
At best you can pressure them at a consumer level to change their output, e.g. their recipe, but you probably can't make them sell their company or retire. They don't answer to you, the consumer, they only answer to themselves.
The only major risk to Wests is a business downturn, but that is already self-evident in a badly performing team, you don't need irate fans to tell you losing is bad for business.
