I don't believe your SERP positions would be affected by the fear of Penguin and a proactive action taken by Webmasters to remove links and here is why...Black Hat SEO's wouldn't remove the links and White Hat SEO's have no reason to remove the links.
There is nothing like White Hat SEO. Anything that is SERP manipulation = spam/blackhat/younameit. In fact, anyone who did link swaps in the past did it to improve rankings even if they swapped links in small amounts and stopped years ago.
Some web publishers react to link removal requests by taking down entire link pages. Has anyone else had that reaction from a link takedown outreach?
I was doing a link removal e-mail campaign recently and some 30% of the 10% who responded removed entire links pages.
Do you think the conversion rate will drop if the email originates from a free email account?
Tried it with hope for automation.
Most replies were: "Email me from a domain.com e-mail address and I proceed."
