Most likely yes. And the annoying thing is that they don't take into account different languages. The AI can recognize words, but not meaning.
A while ago some Dutch person tweeted: "Die Bernie Sanders toch." Die = that, in Dutch. But the AI obviously recognized the word (to) 'die' in English along with Bernie Sanders and just instantly drops the ban hammer. And it takes days,if not weeks to get an actual human to look at your case.
They've applied ML to discern status updates from emails. They've applied ML to recognize speech fairly accurately... This kind of behavior seems far too unsophisticated for that. In the Twitter thread some people are suggesting it's something to do with politics. If that's so, then it likely means hands-on-keyboard-finger-on-scales thing a human would cause.
