The King Protection Group has filed a royal defamation complaint against a Twitter user who goes by the name Sirivannavari Mahidol, Twitter handle @HkooVd, and uses a picture of the princess as a profile picture. 

Activist Sopon Surariddhidhamrong has been indicted on a royal defamation charge for a speech given during a Labour Day protest on 1 May 2022 about access to Covid-19 vaccines, after the public prosecutor ruled that he insulted Princess Sirivannavari, who the public prosecutor sees as the heir to the throne.
