If a post is totally off-topic, it's possible for the Moderators of that forum to either move it to Off-Topic posts or to delete it.
In the SharePoint forums, I and my fellow Moderator Paul Galvin delete ad posts (even if its an ad for a SharePoint product); we move to off-topic the technical posts about other products.
In other words if that post is still there then it is people with Moderator priviledges for the .NET Framework who should remove it.
What you could do is start a new thread *there* that catches their attention in which you request the removal of this post and give a link to it.
