As the comment thread revealed, users pinballwizard, elf, shley24, MTAY all registered in succession to recommend the diary. A further look by us revealed that:
* they had registered within minutes of each other, including another user a bit later, janbaby, who was not among the recommenders,
* the same IP address was used by all of them, and is registered to the Clinton campaign,
* two other recommenders, blues and kmeisje, also registered from the same IP address.
To be clear, and to reiterate what's stated in our Getting Started page: paid campaign staff are welcome in this community, but are asked to disclose their affiliation to a campaign, either through their signature line, a disclosure statement on a diary, or even in the choosing of a username. The fact that all the users mentioned above came from a Clinton campaign IP, but did not register with campaign email addresses, and avoided making comments or diaries, instead only recommending pro-Clinton diaries, strikes us as gaming the system and a form of "recommend astroturf." As a result, we have banned those accounts, and will do so again for undisclosed paid staffers of any campaign if need be.
