Most of the indicated code is no longer part of kbin (unlike Pixelfed's code, to be fair). You can see the similarities in the links provided above. However, I need to thoroughly analyze everything once again to make sure nothing slipped past me and there isn't more of it. There might be a tool that could facilitate this. In any case, it's not my intention to hide the original source, even if major changes have been made. I'd gladly leave information about what the code was based on. I have no problem with that, the only enemy is time.
