Index Of Mature Even Though My Website Is About Beer Should I Filter User Posts?

Even though my website is about beer should I filter user posts? - index of mature

For example, I put this user http://beergogglehell.com/index.php/2009 write ... There are a number of insults at the offices of these words should be automatically replaced or left is because it is really a place for adults at all?

It should also require that people have on them old enough to take up residence before admission?
