Another approach: I had created a prototype for zweeper with a frontend controller. This means that the post / bbcode only contains a placeholder and an ajax call, the frontend controller can map any complex (cachable) display logic based on the ajax credentials.

Advantage: No cache reset necessary
Disadvantage: An additional ajax call for each content to be hidden. So only useful for certain constellations (in the case of Zweeper only a hide bbcode in the first post of a thread / blog).

PS @zweeper: Ja du hättest die Tabelle einfach löschen können, nur dann einmalig den Cache leeren.
