If you comment in my blog and stick advertising in it, your comment will be deleted.
I don’t mind if you plug your company if it’s on-topic. For example, if
I were to comment on restaurants in Toronto, it would be perfectly
acceptable for post a comment and say “Hey, check out my restaurant!”
However, it is not acceptable for you to comment to the same article
and link to a site for financing a housing purchase. That’s spam, and
it will be terminated with extreme prejudice.
