If you've been on Twitter for a while, you've probably run across daily hashtags such as #WednesdayWisdom or #FridayFeeling. Some accounts appear to be using them on the wrong day. Can this be turned into a diagnostic technique?

To explore, we downloaded all original tweets (no RTs) containing #WednesdayWisdom since Saturday morning. We then excluded those containing the names of other days of the week, resulting in tweets from 89 accounts.
A significant subset of those 89 accounts appear to be automated. 33 of 89 are either active 24/7, post 90+% of tweets via automation services/API, or both. There's a decent variety, but some of them do appear to be part of networks (indicated by color). 
Before we dive into the groups, let's take a look at the breakdown of services used. Social Jukebox, IFTTT, and Tweet Suite contribute more than half the traffic, with various other public services as well as things that are likely custom scripts making up the remainder.
First group: @FaithAtheismNub @FutureWorldCen, @WomensPowerCen, and @RevolutionsCen. All four use the same services (Tweet Suite, paper(dot)li), and are operating on more or less identical schedules.
Here are the #WednesdayWisdom tweets posted by the above accounts on Saturday/Sunday. All four accounts posted the same tweet, with only the background of the included graphic differing.
Moving on, we have a group of three similarly-named accounts (@tmj_atl_hrta, @tmj_bna_hrta, @tmj_VAA_HRTA) that appear to link job posts on careerarc(dot)com. One of the tweets is shown as text because it disappeared partway through the analysis before we could screenshot.
Finally, we have @Harrison_Kate10 and @MoneyMonzon. These accounts are both automated via IFTTT, and appear to pump out advertising-esque tweets about online advertising. #YoDawgWeHeardYouLikeSpam
Postscript: these are not propaganda bots - most appear to be commercial in nature. The goal of this thread is to explore techniques as opposed to identifying specific accounts as "suspicious".
