Answer: unsurprisingly, a botnet. We found 19 accounts that we believe are part of the network, created over the course of a little over an hour on December 7th, 2020. All their tweets thus far are replies sent via either "Mobile Web (M2)" or "Twitter Web Client".
The 19 accounts in this reply spam botnet operate on nearly identical schedules, and often send the same replies. Most replies are in Arabic, with the occasional English reply thrown in for good measure. (As always, take the Google translations with a grain of salt.)
Who and what do these accounts reply to? Mostly coupon/discount code tweets from Arabic-language accounts, but there are some exceptions, including @eduofans, a Chinese-language account that (if the translation is correct) appears to be selling social media engagement.

This botnet consists of six accounts with GAN-generated profile pics, all created on August 11th, 2020. As is the case with all StyleGAN-generated face pics, the major facial features (particularly the eyes) line up when the images are blended/overlaid.
These six accounts tweet on nearly identical schedules and (allegedly) post all of their tweets via the Twitter Web App. Thus far, each accounts has sent exactly 10 tweets; with the exception of their first tweet, they always tweet within an hour of one another.
In a bizarre coincidence, this hashtag-crammed @SorabNY tweet was retweeted by a bunch of accounts created in May 2014 with random-looking names. #FridayFeeling
These accounts are part of a 29-account retweet botnet created on May 25th, 2014. All the accounts have names consisting of 11 or 12 lowercase letters, beginning with a consonant and followed by alternating vowels and consonants. We suspect the names were generated randomly.
The accounts in this botnet have thus far posted all of their tweets (allegedly) via "Twitter Web App". Despite being created back in 2014, we found no evidence any of them tweeted prior to September 2020, with most accounts activating for the first time on December 9th, 2020.
We've seen @justinsuntron turn up occasionally in our research on fake engagement networks, so we started perusing his followers to see what there is to see, and found an interesting little group of batch-created accounts.
The botnet we found following @justinsuntron consists of 886 accounts created on September 24th and October 1st, 2020. Their initial wave of tweets was set via TweetDeck, and subsequent tweets were (allegedly) sent via the Twitter Web App. All have female names.
These accounts do four things:
• quote tweet cryptocurrency giveaway tweets (mostly from @justinsuntron)
• retweet cryptocurrency tweets
• reply "good" to a tweet from @OneSwap
• post original tweets composed of random nonsense
Answer: they're part of a botnet, consisting of 12 accounts automated via a custom app called "TweetFoxx". Although they do have occasional organic tweets, the vast majority of their content (19802 of 20233 tweets since September 1st, 2020, or 97.9%) is automated.
The majority of accounts in this botnet operate on very similar schedules. The exception is @TaioSchmid , which is active for fewer hours a day and skips out on retweeting some of the tweets amplified by its compatriots.
We found a group of 22 accounts sending automated tweets linking to soompi(dot)com, created between 2010 and 2014. Although some have older organic tweets, all recent content was posted via automation service twittbot(dot)net.
What does this botnet do? It links soompi(dot)com, and does literally nothing else (or at least hasn't in the most recent ~3200 tweets from each account, every single one of which contains a link to soompi(dot)com).
While looking at something mostly unrelated, we ran across @coinkit_, a tool that allows one to pay cryptocurrency to the first N accounts that retweet/quote tweet one's tweets. We can't help but notice that this appears to be a TOS violation.
The get-paid-cryptocurrency-to-retweet feature of CoinKit is triggered by adding to one's tweets the phrase "@coinkit_ mon" followed by information about how much one intends to pay for the astroturfing assistance. Are folks using multiple accounts to game the payouts?
Answer: yes. We downloaded recent tweets containing "@coinkit_ mon" and found a number of spikes in account creation dates indicating batch creation of accounts. We looked at the largest six spikes, which correspond to five distinct bot/sock networks.
