I don't believe you.
That's a bunch of lies, folks, don't fall for it!
1. Why would he contact him if his only job is to throw some generic dialogs when Icstor gives him the images, like "Oh, yeah, you like sucking this cock, baby?" "I sure do like sucking your fat hard cock, give me more, oh yeah!"
2. Even if we imagine that Icstor did want his opinion about some plot ideas, I very doubt he would just casually ask him for help, because they're not friends, his paying him for work, I'm pretty sure it's something like some amount of money per line of text. But how would he pay for his "consultations"? Like he comes and says, "Ok, I'm ordering 1 hour of brainstorm with you for $***"? And so dozens and dozens of times? I don't think that's what would have happened.
3. Why would he contact him about anything if he didn't work on the update? Because if he had, I'm sure we would have known about it, he would at least have posted some previews, no doubt.
So, I guess the guy is just trying to cover his reputation for working with that scumbag. Again, don't fall for it.
