First off, someone tipped off the video maker that one of the guests of honor was Xusho Wolf, a fursuiter who is completely deaf. Not only did Nitro not compensate their room or travel but Xusho was never provided with an interpreter, which blatantly violates the Americans with Disabilities Act of 1990. My best guess is that Nitro didn't intentionally violate this (probably more out of incompetence as an organizer and not from being outright malicious), but if Xusho wanted to sue Nitro for disability discrimination, they would have a pretty strong case.

Not in the video, but someone I talked with familiar with Nitro claimed he was planning to force the GOH to walk around with buckets for charity donations (using the vague contract as leverage if needed), but everybody willingly agreed to do it anyway so it wasn't an issue. There's even
a video on Xusho's youtube where they walked around the convention collecting. I admittedly just skimmed this one, so no idea how much was in the bucket, but the video has a little donation counter that pops up every time someone puts money in, and it says 27 donations before they hand it to Nitro (on the left in this screengrab).
Next up, another furry and their boyfriend was invited to be a guest and have their room comped, but they ultimately turned it down. They shared a copy of the CCFC guest contract with the video maker, as well as their message to Nitro about why they were saying no:


Take note of how it has multiple typos, how there's no information about what will specifically be offered to the guests (eg what expenses will be covered), and how there's no information about what is obligated from the guests while they are at the convention (eg you're required to appear at x panel). They instead left it really vague with "help where help is needed" which theoretically means Nitro could have asked guests for anything at CCFC and they'd have to oblige, whether it's appearing at a certain event, or to help move equipment around. The furry claims that after seeing this "contract", they turned down the guest of honor spot, yet they were continued to be advertised as a guest for another month or so.
The same furry also claims that while at BLFC 2019 (about 7 months before CCFC), there was someone representing CCFC literally handing out guest of honor applications to random furries. Nitro supposedly told the CCFC rep to only give forms to fursuiters, because apparently only fursuiters were good enough to be guests. While there's no definitive proof of that, this does corroborate with a youtube video I found of the opening ceremonies that clearly shows all the people sitting at the "guest of honor table" were fursuiters. The only non-suiter at the table was Nitro, seen on the left in the second pic.

When the furry confronted Nitro about this, he denied he had anything to do with it. Also worth noting that he supposedly had representatives handing these applications at Furpocalypse 2019 (aka the gross hotel one) and MFF as well, but I haven't found any definitive evidence of this.

At about 9:45, the videomaker starts talking about Nitro working at a smaller convention and how he allegedly siphoned money from it to fund CCFC. There's nothing to verify this, but honestly, it wouldn't shock me at this point. He also goes on to talk about the lack of advertising; Nitro's advertising plan consisted entirely of DM-ing popufurs and saying "hey if you advertise my convention I'll make you a guest of honor".
Finally, none of the locals in Harrisburg had any idea it was happening, and a local news crew only found out about it and made a
pretty boring puff piece video about it because someone attending tipped them off.
