I actually really like the developer's rationale for why they use an anime character as the mascot.

The whole blog post is worth reading, but the TL;DR is this:

Of course, nothing is stopping you from forking the software to replace the art assets. Instead of doing that, I would rather you support the project and purchase a license for the commercial variant of Anubis named BotStopper. Doing this will make sure that the project is sustainable and that I don't burn myself out to a crisp in the process of keeping small internet websites open to the public.

At some level, I use the presence of the Anubis mascot as a "shopping cart test". If you either pay me for the unbranded version or leave the character intact, I'm going to take any bug reports more seriously. It's a positive sign that you are willing to invest in the project's success and help make sure that people developing vital infrastructure are not neglected.

Honestly, good. Getting sick of the "professional" world being so goddamn stiff and boring. Push back against sanitized corporate aesthetics.

hentai?

hentai character

anime != hentai

I smile whenever I encounter the Anubis character in the wild. She's holding up the free software internet on her shoulders after all.

It's just image files, you can remove them or replace the images with something more corporate. The author does state they'd prefer you didn't change the pictures, but the license doesn't require adhering to their personal request. I know at least 2 sites I've visited previously had Anubis running with a generic checkmark or X that replaced the mascot

Oh no why can't the web be even more boring and professional
