Twitter handles @radako and @Fitz_lol suddenly began using NFT profile pictures and tweeting about NFTs at the end of last month. 

Though both accounts appear to have joined Twitter years ago, their follower accounts skyrocketed by tens of thousands within the following weeks. Radako, for example, grew his follower count from 2,806 to 47,021 between December 18 and December 26, while Mr. Fit’s followers grew from 6,496 to 32,793 between January 3 and January 11. 

ZachXBT believes these accounts were either sold or stolen, explaining the sudden turn of events.
