Tennesee congressional candidate has a search suggestion ban on Twitter: Twitter put a search suggestion ban on Robby Starbuck, a Republican congressional candidate for Tennesee's fifth district. Users who do not follow Starbuck cannot find his verified account by simply searching his name or username. However, followers of the account will find his name near the top of the search results. Although it is unclear whether a specific tweet led to the search suggestion ban, the Cuban American candidate takes a hard line against China, big tech and critical race theory.
