Well done Daan, I would tell you that this really bums me out but it doesn't. First, I don't have another site to link back too so it wouldn't make a difference for me.
But I did find it interesting and I did learn something new by reading it. I also have a question regarding your topic, the back link you are referring too, is that a link that you physically put into your post or is it like detected that you might have say a link on your blog page up in the header section under the name and to left a little?
If it is one that you physically inserted into the post then would that not be a form of censorship by making it a "no link" or a non functional link?
I am just curios about things like this, I may not ever have a site to link back too, but in the event I ever do I would like to at least have an understanding about how it works or in some cases doesn't work.
