How do I turn Facebook into a read-only version?
I want it to allow users to read Facebook, but not to make posts.
The Guardian blocklist includes a special category (Facebook: Posts & Updates)that can be used in a block policy to make Facebook read-only. This means users can see and read the updates posted by other users, but cannot post updates themselves when proxying through the Guardian web filter.
The category can be found in the Social and Lifestyle category group. Use the Facebook: Posts & Updates category in a web filter policy with the Block action see https://help.smoothwall.net/Latest/Content/modules/guardian3/cgi-bin/guardian/filteringpolicywiz.htm.
