R: Another Blog reprimanded over a comment

I came across the Blog 'Yawning Bread' which had a legal letter requesting that a comment be removed and their letter posted.

3. The allegations against our client that you have referred to in the Blog Comments have been put up primarily by a person who calls himself “scroobal’ on the internet. The allegations are false and scurrilous.

4. Our client has instructed us to try and trace “scroobal’ in order to sue him. But the internet being what it is. “scroobal’ has been untraceable so far.

5. Likewise, others who have repeated the allegations made by “scroobal’ have so far been untraceable.

6. Our client’s instructions are to commence proceedings against anyone who makes such allegations against our client.

7. We request that you take down the Blog Comments, and publish this letter in full on your website.

Ditto for my blog
