Example: blacklisting "baby" (no quotes) blocks baby animals, #{Vera Baby}, Baby Groot, etc. For some reason, even tags like Babi Rossi and Babi Muniz get blocked. I can see the wallpapers in each individual tag page but clicking more wallpapers or searching for them doesn't provide the correct results.
I'm assuming this is because of how search works right now so this is probably just an unfortunate side effect rather than a bug. I guess baby could be renamed to be more specific or the tag blacklist gets reworked to function similarly to wallpaper tagging.
