It's the one from 2014+ that was managed for a short time by ANGEL_ back when it was called guroch.org, not the 2008 one. I just dug it out of an old hard drive. I'll also look to see if I can find something from 2014-2018 as well.

From what I remember, it went:
1. gurochan.net
2. guroch.org
3. gurochan.ch / gurochan.cx
4. guro.cx

Most of #1 is already public (the post-2010 stuff I think), I sent you at least some of #2 (whatever was preserved, I have more but I stripped out everything but the relevant /var/www and /var/lib files), and I think I have (some of? all of?) #3 lying around somewhere, which I may eventually find.
