I have a hard time envisioning things getting better for Newcastle. You have the sackpardew.com campaign which was probably the closest you'll ever get a protest that was actually noticed since that death threat against Mike Ashley.
Not having the media on your side, like Liverpool supporters had with their previous owners, you're just not getting anywhere.
I'm not say that those who run these protest should give up. But unless you get the national media on your side, along with those 50K+ supporters attending the home games, Ashley will just continue the way he wants....
