AlmightyZenTaco's city tilesets

I was just wondering whether the use of these tilesets is allowed, as long as I credit the author? (You know which ones I mean, the ones from googgoogjob's "Capitalism!")

You'd have to get permission from the author.

I thought Almighty Zen Taco approved those tilesets for public use? I mean, they were on the Public Tilesets Website that used to be around...

They are? Well if you're sure about that, it's okay I guess.
