Sponsor forums active/inactive based on paypal payments?

[NSeXcellent]

I have a few sites with sponsored forums in which I receive payments monthly for. I get tired of being a collection agent and threatening my sponsors that I will delete/hide their forum if they dont pay up. Is there a way to integrate the status of a particular forum so that on the 1st of the month if a paypal payment isn't received from the sponsors account, the status of the forum is set to 'hidden'? This would work like the subscription feature.

If not, is there any easier way to do this with the subscription feature?

Thanks in advance

Wow I feel your pain. I use vbportal to advertise the banner rotations which works nice because you can expire banners and they wont show up but a nice Hack to enable/disable/hide or maybe have the hack send out a sposorship expiring soon reminder.
