Every single algo update same story.
We(other members and me) explained this phenomena few times already and proved it wrong over and over again(just look it up you will find it), some other members did same with this recent change already:

What google is doing is creating global panic, so you do all the job for them and actually claim/report/confirm yourself as a link spammer.
They even invented disavow tool, so that they dont' need to do anything and people in panic will clean their search results for them, among all other things.
If they can distinct spam from actual link themselves then they wouldn't need anyone's help, they will just cut you off.
Same thing they are doing with removing peoples rankings a bit or a lot for sites which they have flags for(site on the fence) and then naturally you will want to know what is happening, then you will read their sponsored articles/posts on the net or just articles/threads/posts from same scared people doing same things and what Google told them to do especially Matt Cutts(LOL) in hope to regain your rankings and naturally you will start removing links,
for those same sites which where on a fence, so they will get confirmation by sudden loss of links and they will know that these are not natural links and penalty will remain if not become even severer.
I'm not saying that they don't know how to recognize spam links, after all they have some big brains there, but they can't do/recognize them all, especially not for sites which are in some gray zones etc.
Trust me you really don't have to pay attention to those updates if you did at least 80% your linkbuilding the right way as explained here many many times. I know I don't care for this stuff and sure will not care in the future.
BTW my sites all all doing fine, as a matter of fact many of them gained better rankings and I'm getting more visitors now and you know what, I'm using links and my tools non stop
They key is to to it properly, that way you will never be bothered with any google update.
Take care and good luck guys!
