Censure you can avoid

Google search as well as Yahoo search have filters that disallow viewing adult contents

Concerning Google search:

-start a search (anything no importance), on the right side a small icon (for the settings) appears,

click it and choose search settings. In it you have the filter item, disable it!

Note: you'll have to do it each time you restart your  PC 
if cookies are not enabled permanently

Concerning Yahoo search:

Almost the same but if done well your settings are permanent.

I just advise to check from time to time.

NO CENSURE OF ANY KIND TO BE ALLOWED
