I expect an open apology at least.
That behavior isn't appropriate even if she had stood him up and they had set a date and everything. Doing this on a public channel seems even more absurd... I can understand if people have bad days and take it out the way he did, but at least they realize their mistake and apologize.
To accuse @heiditravels of being fake is even more ridiculous. I have followed her on instagram where she used to post even before Steemit and also on her Snapchat she verifies her travels.
