Well, on the original topic: The "bot" does appear to have a preference for anime and asian girls, Japanese stuff mostly. It even looks like it's avoiding furry and video game topics. Users will have to upload more stuff themselves to even things up.
Begin rant
The idea that the bot has any sort of preference makes no sense. Because it's a BOT. It CAN'T have preferences because all it does is EXACTLY WHAT IT'S PROGRAMMED TO DO.
And what is it programmed to do? It searches various sites (gelbooru, e621, paheal, etc.) and mirrors everything from those sites that meets the criteria it's programmed to look for (mostly, anything rated explicit, but it seems to upload questionable stuff sometimes if it has certain tags).
If you want to complain about a lack of variety in the bot's posts, complain to the people uploading stuff on THOSE sites, 'cause that's where it gets its uploads from.
