That’s the power of GitHub. The fork still shows idolize as the author and clearly has gpl3 license (added by idolize). They can change what they want in the original repo, but the fork is covered forever, and ironclad proof of the licensing. If OP’s code is based off this fork, unmodified (of which it’s a fork, also ironclad proof it’s that gpl3 version) then it’s also gpl3. Saaaafe. This should be open and shut on github’s end, just a dumb DMCA report.

Nothing at all. If things go south on the install I’ll have a clean slate. Really the only thing I have backed up are keys, everything else is nonessential.

So… I feel ancient just mentioning this, but for literally 20 years now #bookz on undernet has been a solid source for books.

Use something like hexchat, get in the room, search your book, profit. Just got some stuff a few days ago.

Edit: actually, followed JC1’s link in their comment, and it’s a whole guide about how to get set up.
