For some perspective lets revisit Matt Cutts last Summer,
“There’s more data being generated on the web, compared to any other source of data around the web, and I think, the fact is, a lot of people think, ‘Links are dying,’ or ‘Links are not a democracy,’ or ‘It’s impossible to get links that aren’t nofollow,’ or whatever,” says Cutts. “And the fact is, that’s a little bit of a bubble in my opinion, in the SEO industry, because if you look at the actual percentage of Nofollow links on the web, it’s a single digit percentage. In fact, it’s a pretty small single digit percentage. So there’s this perception that, ‘Yes, everything will go social,’ or ‘Links are completely obsolete,’ and I think it’s premature to reach that conclusion.”
I am earnestly asking, how easily do you think that they could identify the OP's pattern? It seems to me that it would have a really small footprint. In my opinion, if he never said, "I'm happy to have some of the Google juice flow his way if it helps him." Google would be okay with a dofollow link.
