Parked ads websites are cloacked or directly optimised for a high ctr?

Hello there,

I have seen a many ads promoting parked domains like that


question is, that one is really advertised an parked domain or its a cloacked one and showing as a white page?

if its cloacked one, which service is it?
thanks.

Mine are just normally parked. I don’t think you gain much by cloaking. I may be wrong.
