What's the answer when a club bans fans protesting in the stadium? Skywriting! Crowdfunded skywriting! Chivas USA fans are clever:
Chivas USA is banning tifos critical of their front office from the Home Depot Center, so screw them, we're taking to the air! They can't ban the sky!
This actually sounds like the plot for an episode of Firefly. If you would like to help these brave rebels in their fight against the core planets, you can contribute to the cause. At time of writing, they're at a little over $600 -- they'll need $4200 to get the writing done.
