Another kind of spamming

I have noticed that my blogsite and a friend's blogsite have been getting comments from people who pretend that they like reading our blogs, and then proceeded to 'casually' leave their business websites behind.
Smart move, people, but you are not doing yourselves any favours.
Do you think people will appreciate the kind of marketing strategy that you are adopting, let alone wanting to use the goods and services you provide?
Your insincerity has already put us off.
And because of this reason, people like me will not even consider visiting your websites, not to say find out what wares you are trying to flog.
Which means you are already losing potential patrons.
There is a time and a place for marketing your stuff, but it's definitely not on people's personal blogsites.
Many blogsites have been created for friends from afar, who would like to be 'in the know' of what goes on in another friend's life from the other side of the globe.
Please respect our aims, and we'll respect yours.
Cheers.
