It is possible, if you use search engine (google etc) and its been cached you can still view pages that no longer exist...for a while.
may or may not last long- when the search engines re visit page the cache will be updated to show newest page (ie where older threads content was deleted by author all youll see is the 'deleted by author' comment). On entire pages that are gone some time caches also disappear.
There are also sources where the entire web is archived...
As I do not know the circumstances or wishes of wazoo Im not posting link. I do not understand 'taking your ball' and going home but there may be and probably more to this than can be second guessed, so not.
I hope though the effort isn't made to remove the remaining older reports that are archived.
