About whether or not there was a fan connection made between ATP07 and Noatak in 2002 (that the supposed 2002 faker could exploit), it seems like the answer is no.
There's this post from 2005 when people are discussing and proposing what the name of ATP07 could be: viewtopic.php?f=2&t=139
No-one posting there connects ATP07 to Noatak, or suggests that could be what the voice is saying.
Also, every post on Twoism mentioning "Noatak" between 2005 and 2011 are discussing fake mp3s, imagining what the Hooper Bay track would sound like etc, no-one mentions that it could be ATP07.
The earliest post I could find where someone suggests ATP07 voice could be saying "Noatak" is audiotrack from 2012: viewtopic.php?p=166177#p166177
People can draw their own conclusions from this, but my own take is that if these really are mp3s from 2002, I find it very hard to see how they could be fake because: stem splitting technology didn't exist like it does now, the ability to clean up that distorting bass on ATP07 as much as this didn't exist (and actually probably doesn't even exist now), and most convincingly for me: there was no reason to make a fake of Noatak that sounds like ATP07, people hadn't made that suggested that connection at that point.
It's still possible that some absolute maniac made these fakes in 2026 and went to very impressive lengths to encode the mp3s in a way that was very typical of late 90's/early 00's era.
