I think if people choose to put themselves in the public domain, and in particular if they try and make money by presenting a certain often borderline fraudulent curated version of their lives then they have to accept that it is an important that there is a counterpoint where it is permissible to discuss the -glaringly obvious inconsistencies in what they put on the public domain.
Particularly people who fundraise or make a living from promoting this version of their life.
I remember mumsnetters doing some powerful work picking holes in the fakery of MLM "boss babes" back in the day. That forensic digging into their posts was so key in bringing into the spotlight how much they were fraudulently presenting an image of success in order to lure new people into their pyramid schemes
There's a healthy balance to be found - where robust critique of public social media posts should be perfectly legal but making up lies or stalking in real life quite clearly should not be allowed
