They define active as having tweeted in the last 90 days.

I'm active on twitter, check it every other day, follow @ElonMusk but I don't tweet. Perhaps I'm a unique case, or their assumptions are a bit off.

Some metrics they consider suspicious (from the article):

1) Accounts that didn't tweet recently

2) Accounts with low number of tweets

3) Accounts with a low number of followers

4) Accounts that didn't set up their own profile image

Lurking != bot, and these data-points would all hit high for lurkers. I'm somewhat suspicious of their results, especially given the results from this pew study suggesting the majority of twitter users don't tweet very much.

25% of Twitter Users Produce 97% of All Tweets: https://www.pewresearch.org/internet/2021/11/15/2-comparing-...

I think it's connected to a more general phenomenon though. Pewdiepie has 111 million subscribers on YT and gets like 3-5 million views per video. Like 95% of his subscribers don't watch his videos.

Sounds accurate if you go through the comments under his tweets, a ton of url spam and scam 'trader' bots

The ratio of fake Elon Musk accounts to real Elon Musk accounts is probably even funnier.
