Three is fairly generous a comment link policy. I personally believe that links to their site need to go in the comments form and not in the comment itself. When it’s there, it interrupts the conversation style of the comments and, well, looks desperate. Millions of dollars are made by human comment spammers paid to create “legit” comments stuffed with links “naturally” so I’m very suspicious. On my own blogs, I delete their links and leave their comments, unless the link is part of the conversation, not the link spamming.

That’s where credibility is lost with me. In the intention of leaving the links.
