The Heartland Institute has issued legal notices to at least two of those who have been engaging in dubious tactics after the faking of the strategy memo became clear.
Firstly there is DeSmog and secondly there is Greg Laden, the blogger who was the subject of considerable interest among Tallbloke's legal team a few weeks back.
...we respectfully demand: (1) that you remove both the Fake Memo and the Alleged Heartland Documents from your web site; (2) that you remove from your web site all posts that refer or relate in any manner to the Fake Memo and the Alleged Heartland Documents; (3) that you remove from your web site any and all quotations from the Fake Memo and the Alleged Heartland Documents; (4) that you publish retractions on your web site of prior postings; and (5) that you remove all such documents from your server.
