@ZellaQuixote We downloaded tweets containing the phrase “credit to the respective owners(s)” and found 61 accounts made July 2019 or later with extremely similar schedules and profiles. There are a few obvious themes, with supposed Native American accounts being the most common. 
@ZellaQuixote The 61 accounts in question tweet via a combination of Tweetdeck and the Twitter website. Although use of the website is generally a good sign that a tweet is organic, it is possible to automate and due to the degree of similarity/repetition we believe that to be the case here.
@ZellaQuixote Finally, we plotted a network in which accounts that had posted identical tweets were connected. This results in the accounts clustering by theme. The African-themed cluster thus far contains only one account and may be a work in progress.
