does anyone know what’s this link for?

看到犯这个语法错误的人真的多，据我 (粗略) 估计在美国至少50%的大学毕业生都会这么说，所以某种程度上说这句话的那位英文是母语水平哦！！！
正确语序是这样的：Does anyone know what is this link is for? 所有这种结构的第二层都需要用正常词序，比如说

• Do you even give a damn about what I need??
• I don’t know what you’re talking about.
• Have you figured out where the problem is?
