Question about gravitational waves

Someone asked :

Since dark matter is thought to interact gravitationally, could clues about it be discerned in gravitational waves?

And Founder of APG ( FAPG ) was answering :

As stated, this is just an idea, In our opinion, this is a misconception

Supplementary : 
Even if we assume that this misconception is acceptable based on general relativity, still in our opinion, it is not possible to discern clues to gravitational waves. (M.Sh)
