Promo membership and non active content

Have an issue, 

Im looking for a way to have something like a promotional membership level, only when it expires, the user along with their content goes 'on hold' instead of the current situation.

at the moment, I can set a user up for 30 days promo membership, but at the end of it they are automatically 'upgraded' to standard membership... I don't see the point in this sort of promo membership...

The other 'issues' I have, is if I de-activate a user, all their content remains. If another user clicks on any of that users content, they can still view their profile even though its 'deactivated'.

Whats needed...

A 'promo' membership, where users can create content, but after a given time period, the promo membership expires. 

When this happens, the created content should not show, unless the user upgrades to a full membership.

Possible under normal conditions?

yeah of course its possible and of course need some coding work done to achieve it.

In inc/membership_levels.inc.php file "getMemberMembershipInfo" function you can code that will check if the current member's membership is set to "Promotional" and is expired. Then you can code a function that will change status of all his content to "pending" from active and call it from there. We need some check to verify that member's content is not already marked pending before calling the function to do the same.

Basic idea...no code sorry

Also look at suspending a member instead of deactivating them.  I think in suspended mode the member's content is not viewable.  I have not really check this.  You would have to remove the part where a member can reactivate their account from suspended mode.
