Depends on which point raised.
For the Dimitri connection it'd be easy with the clip of flam calling him a friend of a show and the twitter convo
@Perspicacity has.
Then the 'real-real' evidence would be the steam groups, just the caps of the groups and the members' pages would suffice. But I suspect they deliberately withheld on doing that, because then they would have been practically forced to pull up the archives as well, and evidence of gay ops, justified or not, always makes observers lean heavily in favor of the ops' target. If they had done this and tried to run with it anyway, they an the risk of their own audience making fun of them for it for weeks.
If you want to blame someone, blame PPP. If the impetus to hold off on it was all Andy, it would have come up in some way, like PPP telling Andy to put it on-screen and Andy refusing. If you watch their show, every time they pull up a clip or a picture, PPP explicitly tells Andy to do so, down to the specific filename. Pegmenco spent like 10 minutes repeatedly telling PPP to show the evidence and he refused to give Andy the ok to do so.
I'm pretty confident the whole reason why they got evasive about showing the steam group was that PPP was afraid of losing face and looking like Bryan Dunn when it turned out that leak he got tricked into raving about was entirely fake. He is, much like the gunt, driven by insecurity.
