If someone wants you to give them your number and you don’t want to, give them this number instead: 647-476-4910 (647 is the area code for Toronto: link)

Edited to add: I just visited the URL they mention in the message. Turns out these numbers are everywhere. Find the one closest to you here: rejectionhotline.com
Now I’m getting the feeling that I’m a little behind the times and this is old news.
