The post cache doesn't affect the user post count. It's a temporary database table that saves the displayed text for posts, so that less processing has to be done to display threads. When you install this product you don't have to rebuild the post cache, but if you don't, quotes in existing posts won't be hidden until the cache expires (I think the default is 7 days). When uninstalling this mod, I believe the cache must be deleted or rebuilt or else the quotes won't be displayed correctly.

When I wrote the instructions I said to use the "Rebuild Post Cache" because it's the only good way to handle it via the admincp. But another way to do it would be to use Execute SQL Query under Maintenance (if it's enabled in the config.php for your user), or use phpMyAdmin, to truncate the "postparsed" table. If I were going to release an update, I would just add code to the mod to truncate that table when installing/uninstalling, but I didn't think of that at the time.
