Ok, so I just started playing (don't blame me, I didn't mean to break half my bones right after the game was released), and, unfortunately, therefore missed the opportunity to make a character on with the EoFFers.

Perhaps it's a side effect of being on a server that is still allowing new characters to be made. But as soon as I completed the tutorial, I found that the gil spammers WILL. NOT. STOP.

The chat bubble is completely filled with gil sale websites, and new ones are popping up every few seconds.

How do I get these jerks to shut up, and why is there no option to report them?

The majority of them seem to be coming as shouts (though I don't know if there are chat channels), so is there a way to block those?
