(MSN) Twitter CEO Jack Dorsey took the unusual step Wednesday of going on Sean Hannity’s radio show in an attempt to win back conservative Twitter users. On Twitter, pro-Trump Twitter users are increasingly registering their discontent with Dorsey by adding a red “X” emoji to their account names to claim they’re being “shadow-banned.”

Like the frog emoji before it — a reference to Pepe the Frog — the X has become a ubiquitous symbol in MAGA Twitter, while baffling everyone else.
