Yes of course.

It is basically a variation of:

"Excessive link exchanges ("Link to me and I'll link to you") or partner pages exclusively for the sake of cross-linking"

plus

"Large-scale article marketing or guest posting campaigns with keyword-rich anchor text links"

in this case, however, RG is "linking to you" from twitter's domain, while receiving links from the blogger's domain.

To google, this is a one way (non-reciprocal; read: "more valuable") link in RG's favor.

It's a set of many links in the bottom of a page, mostly unrelated to the main content of the post. This lights many red flags in the Google webspam metrics, I'm pretty sure.
