Needing to have evidence to not have your theory marked as misleading doesn't disincentivize research into conspiracies. It does the opposite. There would be more research into these theories so that their purveyors could say them without being labeled misleading. Anyone would still be able to do their own research under this model too, they would hopefully just know not to blindly believe what they read.
Investigating wrongdoing and backing up findings with evidence is extremely important. Spouting unfounded lies is not.
