As I have always said, using a no-follow simply tells Google that you are selling links. If this was my algo, I would certainly make it question all your [website's] outgoing links, because why trust you to be honest with the no-follow, when I don't trust you in general?
Ask yourself - would I link to this website for free? If yes, then there is no problem, it benefits your visitors and puts money in your pocket.
Anyhow, I have a few websites ranking only through paid ads and I haven't seen a drop in March, which would indicate that the websites I advertise on still pass juice without issues.
So I only no-follow affiliate links.
There are much better ways to block ALL search engines from following your aff links, even with simple html.
