I can see it, because my settings are set to see dead items.
And it isn't censorship when the code for the forum is publicly available. This is private property, not the pissing ground of trolls. You have no right to post here. You must respect the owners and curators of the site.
I would say the most important reason to kill the thread is that it isn't something you would say to someones face. That rubric works really well to judge whether it is appropriate for a forum like this, trying to host interesting content.
