i recommend getting a browser extension like 4chanx or 4chan-xt and using the filters to hide the recurring spam threads. its the only way this site is usable.
both plugins will automatically show you all the stuff jannies delete as long as the post survived long enough to get archived.

4chan xt: https://github.com/TuxedoTako/4chan-xt
4chan x: https://www.4chan-x.net/
or you can manually read /fa/'s archives at https://warosu.org/ if you're ever curious what the jannies are up to.

the more anons who can see deleted posts, the less power jannies have and the less they can fuck with and lower the quality of our board.
