After having a tech from Godaddy look through my site yesterday, he told me that it looks like the JEvents module has been hacked.
They ran a Site-Lock scan on my site and removed malicious code, etc.
I just added a new event to the site a couple of hours ago, and the casino links showed up in it again.
