I must concur with Parkwise's assessment: I've a vehicle ad posted and received a text msg from this number (1 289 434 4057) requesting if still for sale. His text included the EXACT extended title (wording, caps etc) from my kijiji ad.
I got emails and messages from him too. Says his name is Scott Daily. He stopped replying when I sent him a link to this page telling him I was going to report him to the police
