[Harry Potter: Goblet of Fire] Does the Wizarding World have no way to stop Rita Skeeter telling lies? Could Harry have gotten her banned from Hogwarts during the tournament?

The only institutions with that authority would be the Ministry of Magic, or the Daily Prophet, neither of which have any political incentive to 'restrict' Rita Skeeter. 

The Ministry of Magic uses the Daily Prophet to syndicate pro-government propaganda, and organize (dis)information campaigns. As such, the Ministry of Magic isn't about to politically damage one of its most important allies. 

The Daily Prophet itself, also has no incentive to censure Rita Skeeter. Despite her damage to social discourse, there is no doubt that she is *popular*. If the Daily Prophet censured/fired her, that would upset a non-trivial portion of their readership, for no gain. What's worse, she might join a competitive newspaper, and take her readership with her.

**Tl:DR;**

They could, but nobody really wants to.
