Main thing missing in this thread is that Bots can do things that doesn't involve actively tweeting. Things like liking, following, etc. Even clicking a hashtag has some effect on the Twitter algorithm. Furthermore, the most important metric for Twitter advertisers is Impressions. You primarily pay with impressions on Twitter as an advertiser. Does Twitter show ads to bots/fake/spam accounts if they match the #hashtag criteria or target audience to pump up the impression numbers? Are these are the fake accounts that are lurking around without posting a tweet, but impacting the mDAU? "Active" definition needs to be more precise than simply tweeting. If I were an investor or an advertiser, I would drill into these details.
