Concerning': Mark Zuckerberg trolls Elon Musk on Threads with one-word responses, just like the Twitter owner
- Mark Zuckerberg, the CEO of Meta, appeared to poke fun at Elon Musk for the second time this week.
- He responded to Threads posts with one word — "concerning" — in the same way Musk often tweets.
- It comes after Zuckerberg tweeted a Spider-Man meme following the launch of Threads on Wednesday.
Mark Zuckerberg appeared to take another jab at Elon Musk on Threads, his new Twitter competitor.
The Meta CEO responded to two posts on the site by simply commenting "concerning," along with a crying laughing emoji, appearing to reference the way Musk often tweets.
The Twitter owner has responded to tweets with the word "concerning" at least 26 times, Insider found after reviewing his past replies.
Zuckerberg first replied with that reaction when the social-network entrepreneur Nikita Bier joked about a user leaving the platform and then again when a Meta engineer said that Threads appeared to be censored from Twitter's Trending feature
