When I turn on showdead in my profile settings I can see your post marked as [dead]. So it is a problem with the domain.

Thanks for checking. So it's really been blocked!

It could have been my friend, or a anyone else -- in our case there are (pro-gun) people who are hostile toward our project as well.

This is really unfortunate, if it's so easy for anyone to sabotage your domain or project.
