Here's just how much people have stopped talking about Trump on Facebook and Twitter - Vox.com

Mentions of Trump went down by 34 percent on Twitter and 23 percent on Facebook the week after he was banned from both platforms following the Capitol riot on January 6.

Since then, Trump mentions have continued to decline around 90 percent on both platforms from where they were the week of the riots

(That decline may be even greater than what the current data reflects on Twitter because it doesn’t include retweets and tweets from accounts that have since been deleted, like Trump’s.)
