Stuffing backlinks?

All right guys, I just did a fresh installation for a wordpress blog and downloaded the database to check the data, and guess what I found? Someone stuff a cloak backlink into my wordpress blog!

I had not uploaded any themes into the wp blog, so it should not be the themes, regarding the plugin, I'm sure I did not use any of theirs. Is it a hack or something else?

What's your take on this?

its due to you using the wp auto tagger plugin it automatically adds a backlink to there site to your blogroll

thats weird...

pretty common. That's the reason a lot of people even release plugins and themes. It's an easy way to get tons of good quality backlinks if the theme is good enough. I ip cloak my links, so the users would never even know they were on their blog.
