We found 10 accounts (there may be more), all of which woke up over the last four days and began spamming videos. The accounts themselves have been around for years (and some have older tweets), so it's not unlikely that these are purchased or hacked accounts repurposed as bots.pic.twitter.com/6shzrpLdvr

Although these bots are incredibly repetitive, they don't repeat tweets verbatim (possibly to make detection more difficult.) The tweets seem to be assembled from a set of repeated phrases, with a variety of accent marks being added to the English text (i.e., Happy Nْew Yْear.)pic.twitter.com/vakPjWywF5
