After Dicksquad they just kinda stopped doing shit to Jace, and even the whole Dicksquad shtick relied heavily on outside help from people from other trolling organizations like Hats. I think they just ran out of angles to fuck with him or something. Dicksquad was probably the last really solid thing they've done.
But speaking as one of THE WRITERS - the other one being Gamerfood collectively - mostly their decline was due to them running the same plotlines into the ground over and over again until Jace just stopped taking them seriously. Gamerfood's "Cow" generally dreams these up, but they've kind of started jumping the shark. They kidnapped and threatened this fictional character called "Mike" three different times, and this now makes the fourth time they've "hacked" deaglenation.com. I was there in I think two of the three "Mike" incidents (one of which was the infamous "Jace almost shot up a bank" disaster) The most recent Mike incident involved Jace flat-out saying "I don't care about Mike anymore". I think he just got sick of the paranoid fantasy they were feeding him.
Also, in general Jace has grown increasingly resistant to trolling since around late Summer of this year. I can't even pull a lot of shit on him now, I rarely talk with him anymore. He's just hardening up. I think he's grown used to the idea of being ridiculed, accepted it as some sort of occupational hazard even though he hates it. Or something. I don't know.
