List of steps to reproduce (step by step, including full links if applicable):
Notice that the first search result is https://zh.m.wikipedia.org/zh/%E6%9F%A5%E7%90%86%C2%B7%E8%8A%92%E6%A0%BC
What should have happened instead?:
It should never index mobile sites.
Currently I only notice it with zh.wiki.
