Selling yourself on another's blog is tricky subject.
If you just post a link, it is pure and blatant advertising. And many people hate it. The rest just ignore it.
If you are actually trying to extend the conversation, you need to write a full paragraph on your view of the post you are commenting on, and then another paragraph about why your post is an extension of it and worth reading.
Also, putting an actual <A href where it creates a link out of a part of your paragraph helps to not look like you are blatantly looking for clicks.
Basically what you have been doing is going to a store, and putting up a sign in front of their store advertising your store. It is worse than rude.
If someone drops a link but has a lead up or it's relevant I generally let it slide..! But if you're just going to link spam then get pissy when I ask you not to it's a clear indicator that you had no intention of being part of the convo but rather are being a self serving jerk.. :P
Thanks btw for explaining this better than I was able to.

Ummm...was/is giving out free money...not really spam at all. And it wasn't just a link, it was a comment that was hyperlinked.
