Evildoer, here's what the Toronto Sun reported about that:

"Kathy Katula, the 54-year-old mother of four and grandma of three, said after she was featured in the Toronto Sun about her Peterborough townhall appearance with Trudeau on Friday, trolls and haters have been flooding her Facebook wall with negative comments."

It is not possible for a 'non-friend' to post on someone's Facebook wall.  

This is a fraud, and not a very bright one.
