Could you point me to where there is anything in the logs linking Zorgoth to playing DND with them? I've been rather busy with other focuses the last couple of days, so I may have missed that. If you can get me that info, I'd be happy to ask him follow-up questions regarding it.
As for why we currently believe what Zorgoth has said, this is due to extensive checking of his claims behind-the-scenes by other people working on this. Much of what he has said has been verified by cross-checking it with other conversations and logs we have, and/or going directly to the source (such as checking to make sure mod Avery in the e-sports discord incident was not the same Avery that Bella and her crew harassed.) Additionally, he was in no way evasive during my questioning of him. Finally, he is no longer a TTU student and doesn't have a college career to protect, nobody is going to expel him for being in the same discord as these people.
I didn't ask if he had any proof or screencaps of where she made these statements, but I will be happy to follow up on that with him. As for a motivation to lie, I don't know of any that he might have. There were other allegations I asked him about (such as Bella selling prescription drugs), which he said he had no knowledge of. We do have the screencaps from the Title IX powerpoint where Bella frequently talked about rape and molestation in the original Chess server, which aligns with what he claims about her "constantly talking about touching little girls", along with Zoe's interviews where she says Bella would post pictures of herself as a young girl in swimsuits, etc, then say stuff like she "would totally molest little girl me".
