Thanks for all the comments and feedback.
I’d be really interested to hear the results about the tests mentioned above. However I think we’ll get plausible results and not definitive ones.
Someone mentioned before that no-follow tags on authority sites can have a different behaviour. It’s possible that the no-follow tags on the sites I mentioned above are being ignored. The sites could be doing something stupid, but Google’s ignoring it.
Plus, I think everyone is agreeing it’s not a wise move to do it.
