Not censorship. It's a private board, and if the webmasters decide they don't want to host the DB or any other boards for that matter, it's their decision.
We are participants by choice - if we don't like their choices, there are other places we can go. The guidelines are there and if the webmasters decide to change those guidelines, then we should still abide by them.
I'm just thankful of the fact that we have these boards, where people of like mind can come and share opinions, views, observations, and connect with other people.
