as paid links?

Example: A PR 4 page updates the page a year later with new links. Does Google discredit these links as being fishy?

No.

There are plenty of legitimate reasons to update an older page. For example, an article may have been written in 2010 on a given topic such as "Best Vacation Hideaways in Hawaii". In 2012, another author may write a similar article. The original article author may then offer a link to the newer article stating "for more ideas see [insert new article link].

The above is a legitimate example of why an older article may receive a new link.

With the above noted, almost any authentic technique can be transformed to a black hat tactic. Google has numerous methods for detecting pages which try to manipulate links.

yeah def. But what may seem like legitimate and white hat webmaster to webmaster outreach clearly also resembles paid links. Just hoping to not get penalized for something that represents something else. Which seems harder and harder with every algo update

There are two pieces of advice I can share:

1. As an SEO you should be intimately familiar with Google's Guidelines: http://support.google.com/webmasters/bin/answer.py?hl=en&answer=35769

2. As long as you are following the guidelines in good faith, you should have nothing to worry about at all.

If you sincerely practice white hat SEO these are not things you need to worry about. On the other hand if you step into grey/black hat at times, then you have a good reason to be concerned.

If you're worried about this then ask the site to do a larger content update on their page rather than just changing a link. Get them to add an editorial note that says when the update happened and why.

A lot of "keyword sponsorship" services only change phrases into links and don't actually update the content. Plus if ti comes down to a manual review you've almost got proof that it's not just some crappy links you've paid for.
