Reason: Unnecessary combo tags

Why is the last one blocked? Shouldn't it override the current white_and_black_fur -> black_and_white_fur alias?

Not really a fan of aliasing it to a single color fur since then we're then losing one half the color information.

If it's invalidated instead I'll make a bot that periodically replaces the tag with both colors.

+1 for faucet's bot

Still hoping we get multi-target aliases one of these days. I understand it's not an easy thing to add, so I'm not expecting it any time soon. I just remain hopeful, one day.

Yeah... Me neither. But these tags are, like I already said in the description, unnecessary/redundant. And changing it to invalid_tag/the category to invalid... ehh... I am not a fan of it. I have the feeling Its like an excuse for some people:"I dont care if it is invalid. Someone will clean it up"

I assume your bot is just like: "if: black_and_white_fur, add: black_fur + white_fur", right? But some of those arne't even black, but grey, or other dark colors. (-white_fur / -black_fur)
maybe this should be done by hand. There aren't that many posts tagged with it. I already went through some of them and added it where it was fitting. I can finish it later or tomorrrow.
