The allegations are that you knew that Jamambler.io was doing the mixing and not the mixing platform?
I did know Jambler did the mixing in the background, if that's what you're asking. However, end-clients use other sites to mix, such as Mixtum, not Jambler per se, and partners don't use Jambler to mix in the first place. So, it doesn't fulfill all the criteria to treat it as a mixer.
I don't think BitcoinGirl.Club contacted admin
BitcoinGirl literally said:
It's been months perhaps year, theymos and I talked to each others which is not public.
