Headline is strange. The article itself says something similar but not the same:

> But in a new study, the researchers have found that bots may account for between 45 and 60% of Twitter accounts discussing covid-19.“

Edit: this was more interesting:

> not only were bots gaining traction and accumulating followers, but they accounted for 82% of the top 50 and 62% of the top 1,000 influential retweeters
